I disagree. He's not making his right leg spin. The right leg spinning is also a result, not a cause.
I think he's simply not using his arm. His arm is not moving away from his chest. The angle between his shoulders (a line segment connecting his two shoulder joints) and his upper arm (humerus) is not increasing at a fast enough rate. Avery goes from 60° or so to 110°+. Next (overlapping but with a later start), his elbow goes from 90° to 170° or so. The wrist, the last in the sequence (also overlapping with a later start than the elbow) is last and mostly passive (hammer drill stuff).
This has an overlap to golf. We have golfers who spin because they think that's how they should generate speed. They need to learn to "get their arms across their chest" faster - to "release the fourth accumulator" faster (the same shoulder/forearm measurement I mentioned above, though with a righty golfer, it's the left humerus).
