Kayla Feder and Pat Hendricks Senseis' Pawma demo

An amazing demo by Feder Sensei and Hendricks Sensei:


There is so much to admire in this demo, but one technical aspect that I really appreciate Henrdicks Sensei's throw at 1:52. It's not a move that I see very often, but it seems to be something of a signature of both Feder and Hendricks Senseis. I am wondering if its something they learned from Saito Sensei. In any case, it's one that I'd like to explore.
