Morihei Ueshiba injured any number of his uke, both pre and post war. No one, no matter what their skills can control everything that's going on
I think the point in this story is more that in normal training you're not trying to kill uke. He felt that it would be wrong to demonstrate toned down techniques in the palace, because it was the palace.
I believe it was Gozo Shioda who said that after taking Ukemi from O Sensei at a demonstration, he had to stay in bed resting for three or four days to recover.
