OK, I went back and reviewed the guys you cited. Except for Haas, they all do exactly what you said, my apologies for doubting. Haas, as shown in the picture, seems to have more of a flat wrist at contact. Probably it is a grip issue. The more toward a continental one is turned, it would seem the flatter their wrist would be.
This is something I have been doing wrong for years apparently. I appreciate you setting me right.
