I think the point is that a good (or simply aggressive) player will often do one of two things on the flop, given he knows you'll make this raise with all sorts of AA hands:

1) Fold
2) Reraise pot

#2 is very difficult, and you are at a distinct disadvantage. Your opponent knows the meat of your hand, and may put in that big raise with low draw air, some high+low potential, or simply a much better hand. You will make the wrong decision a significant portion of the time.
