It's highly unlikely that spinning more is the solution.
No argument there. You are the expert here. But what I think has happened is that Mr SG has a picture in his mind of how the swing finish should look, and he is moving to duplicate that picture. Hence the spin forward to a finish balanced on the front leg and on the toe of the back leg and with club pointing down the back.
I think he is not finishing his motion through the ball but is swinging inside out at the ball and then spinning and raising his club into the finish, whch basically does not complete the swing through the ball.
What I'd do to treat this is to have him focus his swing picture on the release and the idea of moving through the ball and what happens right after ball contact and get away from all preconceptions of what the finish ought to look like. If you swing all the way through the ball, the follow through takes care of itself.
When I was first trying to learn the golf swing, Johnny Miller was the superstar of the era and everyone was used to seeing his finish with his body bent into a bow, hands held high and club way down his back. So I tried to emulate that high finish -- even though I was being taught a flat hoganesque backswing! In general, the followthrough will mirror the downswing and this happens if you don't think about it. Here, I think that mental picture of the idealized follow through is causing a partially completed inside-to-out cut at the ball. Of course -- Caveat Listener! :)
