I recall Neji using 128palms in the anime but I don't think he did that in the manga, didn't see it here in these chapt'ers. I believe Neji vs Kidomaru was released as a 2parter episode as a New Years special when it came out so maybe they wanted to hype it up more. Honestly this doesn't matter much but I think there was a plotpoint where Hinata can just barely use 32palms so Neji being able to pull off 128 instead of just 64 makes Hinata look like a bigger shitter, but the gap from 32 to 64 isn't so bad
