That's way too philosophical for me.Pretty close from what i just looked up.
Anyway, from a superficial standpoint, I'm with you. Blending - as I learned the term - is a recognizable approach. I didn't see much of it in the MMA guy (and none of it in the Aikido guy). The pivot outside shown in that video is probably the most extreme version. The clearest version I know of is simply this: I punch with a right round, and you step forward with your right (to my left - close to my shoulder), then pivot as my punch causes me to pivot. If you added a technique with that (just think a simple arm drag on my punching arm as you pivot), you'd be blending your movement with mine to accelerate what I do into something I can't easily resist (too much circular/angular momentum). I'm hoping that's a clearer picture than I think it is.
Others may have a different definition of "blending", and might fit better what the MMA guys is doing in the video.
