This is sometimes called the worst fold in the history of professional poker. We think that is too hard on the folding player. It is impossible to know what the other player might have and what might seem like a terrible fold when you watch it on youtube can feel like the right thing to do when you sit at the table and think you got a read on your opponent.
There is no doubt that this was a weird play and a weird fold. There is also no doubt that the pot odds was more than good enough to stay in the pot. We do however think that there are many other equally bad folds each year.
