I agree that it sounds horrible, more aggressive than dominant anyway, I certainly wouldn't use it. Seems kind of similar to what the ceasar milan guy tries, basically scaring the dog into a freeze. No training/learning involved. When our dogs were puppies though we did exercises where we would hold them on their bellies or on their sides until they stopped wiggling. It was different though as we weren't threatening in any way, just holding them. I think it did a lot of good though with trust and knowing who's dominant.
