Because there is no other grip that allows BOTH the right and left hands to 'naturally' stay in the proper relationships the wedge(s) require, (with the possible exception of 10-2-D). To really understand, you must 'get' 6B-1D - extensor action - it 'locks' the wedges in place.
The difference between B/D is a matter of rotation.
