I'm playing a 480xBB pot with AA, 100NL deep

AA wants to get all the money pre-flop. Against a particularly agro player OOP who you think is determined to get all his money in anyway this trapping play is the same as getting it all-in pre-flop. Not the same, but the results are the same. Bet-call, bet-call, all-in-call. Raising pre-flop may have given him a chance to get away. Calling lets him think he's good. You're not folding and all you want is to get all your money in. I think you trapped him nicely. Results are not important. You'll win most of these, but you won't win them all.
