You're kidding right?
First of all, it's an unspoken, well actually spoken, rule that you play purposefully weak defense in all star games. It's a exhibition, a talent show, not a tournament or combine.
Second, Waiters actually wrapped a dude up in the first quarter (don't remember who) to prevent the easy bucket, and he got side-eyed by a bunch of players. He got caught up in the moment and instinctually tried to stop a dunk like you're supposed to in a real game, and then realized that the etiquette is to just let the dude dunk.
From that exact moment forward, you could see Dion literally step aside on fast breaks. As you should in an all star game.
