I wonder if something similar happens in rowing. Does the contact point shift up with faster rowing? Is it a good idea to try to use the mid foot, as described in that video? Does it all come down to one's own physiology and flexibility?
I have taken the advice to use a weightlifting shoe and noticed that it keep me flat throughout the whole stroke, with very little heel lift. So far, I don't feel any ill effects. I'm intrigued with the idea of using heel blocks on a boat, and will try them if I ever get a boat.
