I would not be surprised if this method was chosen to work around a nasty bug in Gamebryo's animation system or a bad interaction between havok and the animation system. Based on my experience with oblivion and fallout 3/NV, there are way too many ways for animations to crash the game. Of course it could have been that Bethesda was lazy like shown above as well.
