Still Going!

I've found this video a long time ago on A.R.S., and have known it for over a year.
This is the link to the video.
Damn, what strange phenomenon, well, not really strange, but really unusual!
My suggestion for this is that the two tornado clouds were within their effective range of suction; they basically drew or pulled themselves together. Now, my guess here is that they're turning in the same direction relative to each-other; otherwise there'd probably be some upset in the rotation precision, or there would be one tornado terminated before the other; the weaker one going first. But the video is too short and unclear to tell.
Also, there is some 2T22 or 3T22 model in there!
