No they didn't, and they shouldn't.
Again these rules are horribly written because in practice they lay all of the blame at the defenders feet and ask them to do completely unrealistic things in the name of "safety" (which targeting and roughing the passer rules have demonstrably done zilch to promote).
Your second point makes absolutely zero sense considering the coach's contract has absolutely nothing to do with rule changes and interpretation.
While I agree with you 100% about the stupidity of the rule, the bigger issue to me is that the $7 mil-a-year Moon Family HC again doesn't know the rules. Pretty inexcusable.
