Ah, you think he did not have to do any work to get where he is?
No. That's not what I meant at all. My comment was aimed at the work an overly-compliant uke has to do to be overly-compliant and how it can allow nage to move rather more easily and comfortably than he would be able to with a person less familiar with the ukemi and less motivated to make him look good.
I expect Takeda sensei had to work just as hard taking ukemi for Yamaguchi sensei as his own uke have to work taking ukemi for him.
As I said, I am only making comment on this one video clip. There very well may be other clips where Takeda sensei doesn't have such helpful uke and is able, therefore, to demonstrates his power and control over his uke much more clearly.
