I think he means chords which have the root on the 5th (A) string , and chords that have roots on the 6th (E) string.

e.g. :
A maj , root on 6th [577655]
A min , root on 6th [577555]
D maj , root on 5th [x57775]
D min , root on 5th [x57765]

BTW, these shapes (patterns) are the same as open string chords , but you use a barre to play them on higher positions.

The string are in order low to high [EADgbe] , or [654321] .... "x" means to mute the string or not to play it.
