They might be real but what gives off the most suspicion about it is that the names are too... Explanatory, when compared to the animations' names that were confirmed to be real leaks.
0:10 legit Looks Like a 1 shot counter for suiryus ult, where he Blocks a kick with His Hand and then Beats him up, or suiryu ist the one kicking and Its a cutscene, still i think IT one shots
No it's not If you look at his last video he showed an animatioj which could be a new KJ counter move So i'm assuming the "DeflectVictim" is the animation of the person Getting hit by the counter
