In all seriousness I think it is variation of the Cardini "click" change but it uses the same covering action as Parth Dalal's "axis" change to improve angle sensitivity. If you watch from the "Bad" angle (left side) he actually does have a moment of pretty good cover as the meat of both thumbs draw close together. Not saying that is how he does it but I am saying you can accomplish a very similar looking change by making this combination. For all practical purposes the click change is (IMO) more functional. It has only one really bad angle and the clicking sound disguises the sound of the cards sliding.
