Here's how I see it. when WR1 hits the Z in his route, he should be faking (Bort said somewhere, sometime that WRs fake on cuts). At the same time, the name of the play implies that the QB should be pump faking. In that situation, the CB should be biting a hell of a lot more than if he was trailing. If trailing, he shouldn't see the QB at all and, rather than anticipating where the WR is going, he is focused on following. It's a lot harder to get faked when following the WR (or should be). I agree that a stop and go should also create separation, but that's a different animal.
I still stand by what you quoted. If the WRs aren't getting open more (particularly on plays that are specifically designed to fake them open), turning up the PDs will hose the passing game. Taking it a step farther, the CBs appear to need a bump to their PD, particularly on deeper balls. So, you have to give a little to get.
