That video tells me that perhaps we are talking cross-purposes - it demonstrates much more clearly what your are talking about and allows me to clarify my point.

Pat - in my view - clearly takes uke's balance before applying iriminage. You may be seeing one technique but I see a beautiful rendition of Shodokan dogma. Kuzushi proceeds technique. In this case kuzushi is applied through ushiro-ate and irimi nage is applied to an unbalanced uke.

To add fuel to the fire - uke being static is a disadvantage. I would say that a well balanced uke is even harder to throw if he is allowed to move.
