I have seen 3 players who do this move that Hogan showed Schlee. Bill Kratzert, John Mahaffey, and Sergio Garcia. I have swing sequences of Kratzert and Mahaffey that show this definitively. At the End, Kratzert has his hands above his head and the next frame shows his hands have dropped 12" straight down below his shoulder, with his shoulders and hips still fully turned. Mahaffey's drop looks to be about 8".
