The reason that most of us think that the wings and arms would be one is because on Faunus, animal traits seem to be in the same place you would see them on an animal. Cats and bunnies have their ears on top of their heads, so on Blake and Velvet they would be in the same place on their bodies. Bats use their wings and claws similar to how humans would use their arms, so it makes sense they would have wings on their arms. It would also explain why Sun doesn't have a second set of ears, as his animal counterpart has ears in the same place.
