But this move to 2B I would balk because the foot didn't land before the hands came apart. The step is actually part of the throwing motion.

Slow down the video of any MLB pitcher (LHP) stepping at and throwing to first. When the foot lands gaining direction and distance, not only are the hands separated, the throwing arm is beginning its move foward.
