Well it would be if it were applicable in this case but I see no evidence of it. Firstly, I saw nothing to suggest the referee was acting on the advice of the AR - from what I saw, especially on the replays, it appears equally plausible that he was just giving himself time to consider his decision before blowing up for the offence.
Secondly, if he did take advice from one of the AR's it was surely the one that was ahead of him and to his right and who was positioned (as he should have been) in line with the second-last defender, giving him a relatively good angle to view the incident. Also, with a pitch width of 72 yards at Villa Park, he was probably around 40 yards from the incident rather than the 60 or so you seem to be implying.
Anyway, I'm more inclined towards the "giving himself time to think" option, given what I saw of the game.
