What kind of guard is this? (Link attached)

Hey what's up guys.
Just wondering if anyone knows what kind of guard Sonny is playing/sweeping with in this video:

The one I'm talking about is the one where his left leg looks as though it's in a backwards Delariva with foot on hip, with right leg butterfly hook? Happens in the beginning and towards the middle of the video. Is it a weird twist on already existing guards (half, delariva, X, etc.) or something totally new?

Thanks!

Around 0:33? Looks like just a setup to push them over for an ankle lock/hh.

Looks like he's going for a heel hook to me...

First he plays halfguard with the butterfly hook.

The rest of the sweeps come just from the leglock grapevine that others have pointed out.

Leglock position ... often used like a guard, especially in nogi.
