Hmm, interesting --
So it seems that, as a result, the torso is in a position more similar to standing. That is, rather than the torso's front (rib cage & tummy) being compressed, it's allowed to move more freely.
When I sit & play, even though my back rests against the chair's back, I put my feet back almost behind me, which ends up rotating my hips just as you describe.
