The nature of the overhook on his arm pulls his entire torso to the side, effectively pressing the side of his neck into the forearm that you're driving down, so it does pressure the artery there and I've felt light-headed from an Invisible Collar before.

I have the Twister, I think Bravo is a druggy and his comedy is kind of sucky, but his Jiujitsu is still awesome.
If you're squeezing inwards with the leg, you could be pushing the shoulder into the neck on the other side, thus cutting it off like a triangle.

I think I'll grab a willing dummy and give it a try tomorrow.
Err, try out an invisible collar first. I don't see how you can put any appreciable force into their other shoulder.
