Maybe I'm missing something...If I throw my right hand with my weight on my right foot, and my left heel off the floor whirl my shoulders to the left, in order not to tip over or something similar, wouldn't I have to, at least briefly, put my weight onto my left foot, since my shoulders are turning to my left, and wouldn't I have to pivot my right foot inward to turn my hips in the same direction as my upper body?
It sounds to me like you are talking about building the punch from the top down, instead of from the bottom up. That may be me not following...
