There are tons of things like the 4for4 in print. None of which are very streamline and miss several of the important details in making it invisible. I have been doing that move over 25 years. Mine was in print years before the card college series started. I don't have the books so I am not sure what it means by he thought of it. Does it say in the book that this is his move he showed it to me and I ripped him off. FYI only met him once in passing and have never seen him perform. Does it even mention the 4for4 switch. I am not sure what you are insinuating with your post. Mate
It is very strange how things go when you put something in print. I showed the 4for4 switch to Marlo with a few alternate handling ideas in the early 80's and they showed up in print 6 months later with no mention of me. I never really cared because they were not as good as the way I was doing it. He just made a move that did not look like a move. go figure.
