Just checked that bug. It seems like you can input any! special and add 6H + your special button at the end to get this bug. Doesn't work with 4H unless your special binded to H (you'll get FD or SB).
Few examples for Axl:
[4]6H -Rashou
[4]6S+H - Rensen
6236S+H - S Benten
632146S+H - S Raieisai
63214H - H Raieisai
That bug is 1F. If you input 6H earlier, you'll get special. Later - opponent throw you, but you'll break throw without performing special.
Wrong again. Button priority didn't change.
OS FD was 4H~P/K/S. If you can throw, you are throwing.
If you can't, your 5H will be karacancelled with FD.
And since GGXXSlash you can't karacancel 5H into FD
"1F jump" cancels last frame of jump startup when character actually become airborn. You can't cancel pre-jump frames with FD.
That last frame you also can cancel with TK specials.

there is no characters with 2F jump. fastest jumps in GG is 3F
About 623P
It has ~10 frames of autoguard part and ~8 frames of startup on hit part. It does ~ -2 on block.
He can cancel his 623P to FB during "hit" part even without attack to GP.
Still 623P doesn't guard low
About FB Kyoku
~8-10 frames of startup
Well, that move can comboed from f.S, 5H and 2D.
But for example 2D FB Kyoku doesn't has any follow-up cuz opponent recovers at the same time with Axl.
After f.S and 5H, Axls try 6K - fail, 5S - fail due to range of c.S, 5P - mostly fail due to whiff on second hit of 5P so they all drop this combo, 2S - no one does not even try it.
But well. Rensen is faster now so it's always can combo from f.S and Axl got those 2K f.S, 2P f.S and 3P f.S combos into rensen.
About Bomber
With FRC he cancel about 12-14 frames of recovery
I think that move lvl5 now so it's 0 on block without FRC. I don't saw that move on block though
One hit 3P CH float lower. Pretty much #Reload style. Hard to combo.
