I have never heard of this method, and like everyone else has said - I really don't see how it can possibly teach your dog anything
We use the "bell method" and I can guarantee it works!
We have a bell tied to the backdoor handle and when Biff needs to "go", he rings the bell. So darn simple and effective - I'd like to shake the hand of the person who first thought of it
