that has been demonstrated here many times is that people often see what they want to see.
Hogan rolls his lead foot onto the inside edge but his heel never leaves the ground. When you look at the video frame by frame you can see that his heel never moves up and only the outside edge clears the ground. It is the same in the full swing video of Hogan in front of the grid and in home video of Hogan taken by some friends when he vacationed with them. His lead foot rolls to the inside edge in the back swing and to the outside edge in the through swing.
