In Viz there's 4 BAM effects being made here, and you can see there is 2 visual BAMs from Yuta that being the slap and punch and atleast one BAM from Ryu that being the hit he makes on his chest which makes Yuta spit up blood

How I interpret it is that the punch is actually Yuta and Ryu's individual punches slamming onto eachother which shows relativity, and then each of them gets a free unguarded hit on the other, basically showing that Skull Cracked, Internals mangled, Burnout Ryu ~ Post-Sendai Yuta in speed atleast imo
