Concerning the start-up picture (top row - right).
Doesn't the toe of the club pointing up indicate that he is using horizontal hinging ? If that is so, then the left foreman must have swiveled (clockwise). Also, with only a small amount of extensor action, the left wrist would become flat instead of bent (4-A-2).
It also looks like that his left wrist is flat at the end position.
