What is wrong with this picture?
Why and how would this never happen were both parties to have a connected body and ki?

Hmm, looks like tori is bracing on the back leg, locking his upper body tight, and probably using momentum. Uke... well, who cares, although if he had connection his structure wouldn't be broken by tori doing this type of thing.
If tori were applying internal strength (rather than simply training it, for example), he wouldn't have his feet flat on the ground.
