There is no rule in either ruleset about a back drawing the defense into the NZ.

Forgive me Mike, I presume not everyone is as anal as you seem to insist on being, nor limits any explanation to specific wording.

Not sure of your experience, so this might come as somewhat of a shock to you, but there are players and/or teams that actually work very hard at deliberately trying to mask "simulating action at the snap" so as to draw their opponent into a foul situation. You may even eventually discover that deliberate attempts to draw an opponent into a foul, thereby creating an unearned and undeserved advantage is not as rare as we'd all hope it would be.

When you've done this for a little bit, you may even learn that proactive intervention is sometimes necessary to prevent endless repetition of negative behaviors, and not everything we're expected to do is spelled out, explicitly by rule.

As for two identical instances producing different results, the part you seem to be missing is, if you handle the first instance properly, you may avoid having to deal with a second instance.
