And of course the difficulty is this - does he know that what he is demonstrating is actually not what he says he is demonstrating?
Josh and others,
Two quick thoughts as I watched the video clip and read the posts in this thread...
1) Judging from Ikeda Sensei's appearance in the video (I've been going to his seminars for 20+ years), I would say that the event filmed was not recent but a number of years ago, quite possibly before 2005/2006. That is important because Ikeda Sensei didn't encounter Ushiro Sensei until 2005, and he has commented several times that meeting Ushiro Sensei and participating in his classes gave him a new language/conceptual framework for what he was working on in his own aikido.
2) My own observation of Ikeda Sensei's teaching over the time I have known him is that his use of language changes as he keeps exploring a theme for a period of several years. So what he says during a seminar now is different and often clearer/closer to the mark than what he was saying back in 2007 or 2008 when his seminars underwent a significant shift to the IS/IP perspective.
So the answer to your question and others related to it may lie, in part, in placing this particular video clip in the context of when it was filmed.
My $0.02, for what they are worth...
