Well, yeah, that's not much to go on. But then, he was applying those techniques with "textbook" aiki-sage, aiki-age and age-aiki-sage delivered in a manner consistent with that line of Daito-ryu. For someone who stated that he didn't understand what Ueshiba was talking about until late in life, it seems evident to me that Shioda did not get his meat-and-potatoes aiki from Ueshiba, but elsewhere... and then he understood what Ueshiba was talking about.
Hah, I think some cherry picking may be happening. I suspect more facts may revealed about this in due course
