The title's a bit misleading, as there's no actual competitive nature to the demonstration.
Clip itself is alright. Kicker didn't really seem to follow through with a lot of those. The irimi body movement against the kick to the thigh did not seem right. I'd be interested to see that with speed and power.
Speed and power from the Uke will be countered with speed and power from the Nage. And people will get injured...
Same thing applies for resisting.
Which is bad for training.
I think the clip is just fine as it points out that there are ways to defend against kicks which you rarely get to see otherwise.
The clip is meant as demonstration and should be taken as such.
