He’s gotten confused. The Roman Catholic editions of the Bible and Protestant editions have the same list of commandments, but the Roman catechisms and Protestant catechisms tend to number them differently, one from the other.
Douay-Rheims 10 commandments
Exodus 20
1 And the Lord spoke all these words:
2 I am the Lord thy God, who brought thee out of the land of Egypt, out of the house of bondage.
3 Thou shalt not have strange gods before me.
4 Thou shalt not make to thyself a graven thing, nor the likeness of any thing that is in heaven above, or in the earth beneath, nor of those things that are in the waters under the earth.
5 Thou shalt not adore them, nor serve them: I am the Lord thy God, mighty, jealous, visiting the iniquity of the fathers upon the children, unto the third and fourth generation of them that hate me:
6 And shewing mercy unto thousands to them that love me, and keep my commandments.
7 Thou shalt not take the name of the Lord thy God in vain: for the Lord will not hold him guiltless that shall take the name of the Lord his God in vain.
8 Remember that thou keep holy the sabbath day.
9 Six days shalt thou labour, and shalt do all thy works.
10 But on the seventh day is the sabbath of the Lord thy God: thou shalt do no work on it, thou nor thy son, nor thy daughter, nor thy manservant, nor thy maidservant, nor thy beast, nor the stranger that is within thy gates.
11 For in six days the Lord made heaven and earth, and the sea, and all things that are in them, and rested on the seventh day: therefore the Lord blessed the seventh day, and sanctified it.
12 Honour thy father and thy mother, that thou mayst be longlived upon the land which the Lord thy God will give thee.
13 Thou shalt not kill.
14 Thou shalt not commit adultery.
15 Thou shalt not steal.
16 Thou shalt not bear false witness against thy neighbour.
17 Thou shalt not covet thy neighbour’s house; neither shalt thou desire his wife, nor his servant, nor his handmaid, nor his ox, nor his ass, nor any thing that is his.
Authorised Version 10 Commandments
Exodus 20
1 And God spake all these words, saying,
2 I am the LORD thy God, which have brought thee out of the land of Egypt, out of the house of bondage.
3 Thou shalt have no other gods before me.
4 Thou shalt not make unto thee any graven image, or any likeness of any thing that is in heaven above, or that is in the earth beneath, or that is in the water under the earth:
5 Thou shalt not bow down thyself to them, nor serve them: for I the LORD thy God am a jealous God, visiting the iniquity of the fathers upon the children unto the third and fourth generation of them that hate me;
6 And shewing mercy unto thousands of them that love me, and keep my commandments.
7 Thou shalt not take the name of the LORD thy God in vain; for the LORD will not hold him guiltless that taketh his name in vain.
8 Remember the sabbath day, to keep it holy.
9 Six days shalt thou labour, and do all thy work:
10 But the seventh day is the sabbath of the LORD thy God: in it thou shalt not do any work, thou, nor thy son, nor thy daughter, thy manservant, nor thy maidservant, nor thy cattle, nor thy stranger that is within thy gates:
11 For in six days the LORD made heaven and earth, the sea, and all that in them is, and rested the seventh day: wherefore the LORD blessed the sabbath day, and hallowed it.
12 Honour thy father and thy mother: that thy days may be long upon the land which the LORD thy God giveth thee.
13 Thou shalt not kill.
14 Thou shalt not commit adultery.
15 Thou shalt not steal.
16 Thou shalt not bear false witness against thy neighbour.
17 Thou shalt not covet thy neighbour’s house, thou shalt not covet thy neighbour’s wife, nor his manservant, nor his maidservant, nor his ox, nor his ass, nor any thing that is thy neighbour’s.
Clearly both translations have not only the same commandments, but have them versified the same.

The Ten Commandments from the Book of Common Prayer Catechism (Anglican)
The same which God spake in the twentieth Chapter of Exodus, saying, I am the Lord thy God, who brought thee out of the land of Egypt, out of the house of bondage.
I. Thou shalt have none other gods but me.
II. Thou shalt not make to thyself any graven image, nor the likeness of any thing that is in heaven above, or in the earth beneath, or in the water under the earth. Thou shalt not bow down to them, nor worship them: for I the Lord thy God am a jealous God, and visit the sins of the fathers upon the children unto the third and fourth generation of them that hate me, and shew mercy unto thousands in them that love me, and keep my commandments.
III. Thou shalt not take the Name of the Lord thy God in vain: for the Lord will not hold him guiltless that taketh his Name in vain.
IV. Remember that thou keep holy the Sabbath-day. Six days shalt thou labour, and do all that thou hast to do; but the seventh day is the Sabbath of the Lord thy God. In it thou shalt do no manner of work, thou, and thy son, and thy daughter, thy man-servant, and thy maid-servant, thy cattle, and the stranger that is within thy gates. For in six days the Lord made heaven and earth, the sea, and all that in them is, and rested the seventh day: wherefore the Lord blessed the seventh day, and hallowed it.
V. Honour thy father and thy mother, that thy days may be long in the land which the Lord thy God giveth thee.
VI. Thou shalt do no murder.

VIII. Thou shalt not steal.
