Did I get this right?

Perhaps not so much a wideout, but a setback "exploding" forward for one step, then turning into a legal motion pattern is likely doing so for the express purpose of inducing a false start by the defense, especially when there's "short yardage".

It's a move that can catch us by surprise, which is why it's a good idea for officials to converge, briefly discuss and agree on who the guilty party actually is on FS/Encroachment situations.
