I'll hazard the expense of pixels. You can see that -- but you can't see the chopstick ?

Motion and stress are equivalent and interchangeable. By EITHER dropping weight (in visible motion as he does) OR setting a line of equivalent stress in the same orientation (i.e, -- in juuji -- right angles), the effect is the same -- if you let the torsional shear take over to cause a slight gyration in the contact angle. The attacker's support (in the video) tends to shear away behind him (like the chopstick) -- his push is mainly cancelled by adverse moment at his base -- not leverage at his contact. It's the same thing -- just looser. Only a shear can do this.
Well, to me that pretty well describes the external mechanics but knowing more about what Gleason Sensei is doing internally, what Dan showed us in August, this is the kind of thing that makes me believe you don't yet see the difference between external and internal--or more correctly, you don't yet see that there is something different going on internally than what appears mechanically visible.

Watching Shioda's tippy-toe randori -- is like watching some elfin rhinoceros doing demolition ballet, and often shearing the base toward instead of away. Shioda often tends to like going up (releasing the compression spiral and extending), instead of down (releasing the tensile spiral and retracting or dropping). But it's all still the same action. Action in one spiral is potential in the other. Both stresses are always available if you start in shear, and initial up or down orientation of action is equally available if you start in tenchi.

Both the tensile spiral line or the compression spiral line can draw the base in any direction, depending on only a slight imparted gyrational moment -- supplied by the shear torsion stress itself. As Endo shows (and as push-hands does), these stress-and-motion lines easily alternate continuously and seamlessly -- in-yo ho and if not compensated by the same mechanism, cause waves of progressive joint buckling -- up to and including the juncture at the base of support.
Again, a lot of this sounds like more or less external mechanical description of physics and the IT usage has a different motive than the externally visible movement. And to my eye, Endo Sensei's movement also reflected that. What I saw there looked like something of an external approximation of what Akuzawa does in a very different way. The relationship I felt between Endo and the uke didn't look to be of the same quality as I've seen and felt with Ark and Dan.

Please tell me you guys really can see all this ?
Yes, I can see what you're saying, but it only describes the measurable physics of the mechanical event--not the internal movement that initiates the outward action you see as the effect. So, yes, I see what you're saying, but it doesn't lead me to believe you have yet seen what most everyone else is discussing.

Sorry.
