How long has H3 been acting as 33? I was wondering why I kept getting 33 motions when I didn't want to and I noticed this silly buffer "shortcut". Try it yourself. Tap H and hold down 3, then press the button. You'll get the 33 version of it. Try it on Hitomi or something. I'd get 33P when I was doing H3P and 33T when I was doing H3T.
EDIT: Basically block standing, then try to do 3T with Hitomi by letting go of H after you've inputted 3.
