Nope, neither of those two attacks have any noticeable issues, possibly because they both do damage and then cut straight back into an attacking animation. However, at one point he killed someone on the last strike of his combo, and as soon as he did the damage, the animation immediately stopped and he walked a bit before going into his 4 jumpy dashes. This was visible to P1 and P2, at 3:32 and 2:10 in the video.
Also, another new thing. When he does his 4 jumpy dashes, if he is against a wall and dashes for a player against the same wall, he can dash up or down instead of sideways, as shown at 0:45, which seems like odd behaviour. If it isn't, then that can bug out even further, with him going up on P2's screen, whereas sideways on P1's screen at 2:25. This happens twice in the same jumpy dash combo.
Oh yeah, the audio is out of sync a bit, and is of the host (the smaller screen).
