I wasn't at the bobcat, and I didn't have a dog in this fight. But after I watched this video, It defantly looks like a choke to me. With the front headlock, then turning the corner to put pressure on the neck down and away, cuts off the air, and the match should have probably been stopped for PD before the bottom wrestler even went to it back. The rule book clearly states you can not put pressure or twist the neck or throat.
