I have a question about "no calls"

While watching critical moments of Saturday's game in slow motion, at the 4:50 mark left in the 4th quarter I noticed that Bama's right guard led with a straight arm to the face and pushed JJA's head straight back, then he grabbed a handful of jersey as JJA started to get past him, and finally grabbed him by the face mask for that last bit of insurance to prevent his QB from getting an up close and personal view of the number 99. There are multiple angles that demonstrate what happened, although ESPN carefully coned down the last, best and only slow motion view so that Ajonye was just outside the frame and we could concentrate on Russell's fancy footwork. Anyway, after that very effective sequence of 3 fouls from his lineman, Russell did manage to get to the outside and complete a pass for 13 yards to get Bama into field goal position. Two plays later the fateful pass interference no-call occurred that apparently rendered everything else that happened in the game null and void.

It raises an interesting question since we have heard practically nothing about Bama no calls. If a single player commits two 15 yard penalties and a 10 yard penalty on the same play, is that considered offsetting penalties and thus the infractions don't count and the play continues? Maybe if the officials can't decide what to call in a case like that, they can just give the offending team a mulligan? I know there must be a logical reason that Herbie and Fowler didn't mention it or show us a special close up view of JJA getting mauled, in slow motion with commentary from the rules expert.
