Awesome analysis. In his start against the Angels, FSNorth showed him "recoiling" after many of his pitches as well. Instead of striding through the pitch smoothly, he would essentially bounce back off of his plant foot and back towards the rubber after most of his pitches. I suspect this is a symptom of the same problem - i.e. being out-of-balance with his plant foot, but just wondering if you noticed the same thing and/or if there's another mechanical issue causing the recoil at the end of his motion. I unfortunately didn't play close enough attention last night to see if he was still doing the same thing or not.
