I suspect you misunderstood Pat's diagram. It shows both the push out and the following one-rail kick. The push out is in solid lines and ends up behind the 5 ball. The one-rail kick that follows is shown in dashed lines.
FWIW, I also though PJ had lost his mind (or what little is left of it:winkor was joking when I first saw his post: http://forums.azbilliards.com/showpost.php?p=5269142&postcount=7
It is an interesting style of move if you are trying to con your opponent. You make a "mistake" that forces you to play a "lucky" shot. You beat your opponent by stumbling through the rack with mistakes and lucky shots. I think my shot after the 1 ball would be to bump the 4 ball while making the 2 in the corner and "trying" to go three cushions for the 3. I'd be sure to move the 4 over to the side rail by the pocket. Lots of possibilities in this rack.
There is no push out or 1 rail kick in the post I saw, just a diagram of a 5 rail kick from the place he could push out from or play safe.
