Or he could be thinking, you're squeezing with some random hand and decide that by 3-betting he's going to represent a donkish AA or KK, and assumes you will fold everything other than AA or KK.

I played a very similar hand to this, where some LAG opens for 80, 5 callers. I raise pot with AKs from BB. Folds back to last caller, who shoves. I called and he had QT. Now that's not to say shoving in James282 is automatic, but I think that if he plays decent, his range in this situation is alot wider than just AA or KK.
