I'm pretty sure that "snap" Ueshiba has in the video indicates something internal. But he also clearly bent down and "jumped" up...
Not knowing how to "snap" like that, let alone "jump" without bending the legs, I don't know if it's the same thing or not.
Not regarding the "snap" in Ueshiba. But regarding the "jump" by Dan without bending the legs. I don't think they're doing the same thing, but the Ueshiba reference helps people sort of visualize the movement. Guess that didn't work out as well as I had thought. LOL.
