Crazy combo!
At first I thought it was skmatw - matw nt
but then looking at it again, I think it's clear to me that it's skatw - satw - amatw nt
I just played it back in 15% speed and there is no co movement. leg goes over too late to be even considered an attempt at skmatw. It's just that he has insanely quick legs that it looks like they just float on the ground. Quick hopping htws (htws were you actually hop, not staying flat footed on the ground) are not amatws.
