I think watching this instructor makes Hirano's rhythmic work make much more sense. He (Hirano) appears to have been decomposing whole-body motion into its constituent components and drilling each technique with each movement component - the thesis being, if tori is skilled enough at fitting with each of several components then he will be able to fit with chaotic-seeming motion that is made up of those previously-understood components.
Check out the last 3 throws on the video - tori spazzes out (chaotic motion) and then finds the throw inside the chaos.
