It's true that he simply might not be wearing the cape he was wearing in 495, but in the frame in question, it looks like his hair cuts off at the back of the neck as well, and unless he's got Kenpachi's super hair-growth hormones going on, I don't see how it's possible for him to have grown it that far out in a few days. The only other explanation I can think of is that he had the rest of it tucked underneath the hem of his cloak, but man, that would be uncomfortable.
