Given the specific nature of the Big Game format, I can understand this play and not wanting to try and tangle with 2 very good tournament pros post-flop. However I think I'd rather have seen him just spaz-3bet-squeeze-shove here instead of fold. It still takes away the post-flop decisions and I don't see 66 or 44 calling off in this spot. His squeeze could have netted him another $6k or whatever it was out of the hand. Quads are extremely rare. Getting PP's 3-way is less rare but still uncommon. AA is pretty rare too. Combining all that, you're talking about a bad fold in almost any other situation, short of a DON/satty bubble or maybe the bubble of a life-changing pay jump in a huge tourney when on a short stack.
mind you if hes going in 4/5 way he doesn't really want to be faced with a wet board for potentially alot of his money come the turn., he has to beat 8 cards with just one pair....
Outside of this unique situation or those mentioned above, I have to disagree with you. I'm still amazed at how many people try to justify folding AA preflop.
The end-goal in poker is to get the chips in as a favorite. While multi-way AIPF with AA dilutes its
equity and might make for an uncomfortable situation, it's still a favorite over any other
hands, meaning you win more often than not. Which is exactly the sorts of decisions you should be making. You can't really wait for "a better spot" with AA because you only get it 1:220 hands on average.
Again, I get the fold on this particular situation, but this isn't your typical poker/tournament situation.
