to make the limbs more dynamic. Set up everything as usual, then press your hotkey and save the pose. It's easy as that. And it adds so much realism! Especially if you set up timeline poses for each position without transitions there is no reason to not use it.
Do me a favor and try it e.g. on 'Mouth Fuck 4'. You'll be pleased...
