I have looked at his motion many times and could not discern whether it was hitting or swinging. I have always leaned towards swinging. It appears he uses horizontal hinging in his follow through. Or could he be swinging using an angled hinge. A swinger could assemble at the top also. I am still not sure. What else makes you think he is hitting, has he ever made a comment that he pushes? Sometimes it is hard to tell.
