Blending doesn't seem to resolve anything at all. Yes, you avoid the bull, but he is still "in the fight".
I agree with the idea that blending itself doesn't resolve the fight...unless you mean blending to include the wills too. I think it was described pretty clear in another thread that simply avoiding an attack isn't aiki. When the bull eventually gets tired and stops the attack, that's when the conflict gets resolved.
I'd say blending physically is the "easy" part. Removing the will to attack is much more difficult.
But are you really blending as you enter during or after the irimi, or is there something else going on?
I can't speak for William's take on it of course, but I'd say that ideally one ought be blending throughout: before contact, during contact, and after contact has been removed so if another attack is launched, you're already in position.
Hope that's along the lines of what you're looking for.
