I don't remember Khabib getting to side control in the first sequence (there was a reset somewhere in that sequence).
Also, you don't necessarily have to close or cross your legs to finish a guillotine.
Nate Diaz does a certain kind of guard (forgot the name of it) to finish guillotines.
The pivotal maneuver Khabib did to avoid getting slept was the thing he did where he fell to his hip for some kind of readjustment. That's the insight that would be really interesting here.
It's a very high level grappling technique that's very rare in MMA.
Khabib's submission grappling is top tier. It's incredible.
