That cloud is actually the "rotating wall cloud". The entire thing is not the tornado. I have seen it reported to have produced a "small brief torndo" and have also heard it did not touch down at all.
Can also watch a youtube video of the same cloud here
it's about 3 minutes in(past the dog video as the guy is fixing the camera)... but you will understand better that it isn't a massive tornado after you see the vid. At 5:36 in the video... the cloud is almost on the ground, but not a tornado.
