HELP! Toru Miyazaki Trick


Hey guys, I can’t seem figure out how to do the slack reverse gt trick Toru does in the videos below. I’ve slowed it down and it still doesn’t make sense. Has anyone figured it out? It would help a lot if anyone can give advice or make a tutorial for the trick.

trick at 2:10 - 2:14

trick at 1:16 - 1:20

Any help is appreciated.
