I wish I could find it on youtube but Keenan basically plays this position as a guard. It's pretty cool. There's a roll he has with Rafa Mendes training for the last ADCC where Keenan just plays this "guard" the whole time trying to invert through to the back or to honeyhole or to kneebars. He gets darce choked by Rafa a couple times but he also has some success with it. If anyone likes the transition in this video look for Keenan Rafa ADCC on youtube and see if you can find anything.
