Excellent slowed down clip. Wish I had some easy clipware.
For clarification in that regard, I was actually analyzing the first example of this technique in Mike's clip, where uke was pushing with his left side, whereas the second example you clipped shows uke pushing with the right.
In this case, chirality does not break symmetry, so if you view David's clip vice the first example in Mike's just swap the L-R orientaton in my analysis, etc. and it is the same dynamic.
