This is how I always looked at it.

DAS took one mesh and made V3,A3 and M3.

So you have a girl and a boy with the same mesh.

Now add a lot of morphs.so you have a girl / guy from skinny to healthy to model to body builder.

But none of them bent perfectly but better then the rest.

I would imagine they had to compromise on the rigs some to get one mesh to do all it does do.
