Yes. It looks like it feels good to me! Certainly stimulates the blood vessels-that's obvious! People are into all kinds of different things, and like Deb said, if they're legal and consensual I have no problem with it.
I just had a massage this week and the masseuse finished up each section with some pats that were similar to this. It felt great!
I became interested (as I sometimes do) in what was behind the video and found this: a French video with over five million hits. I believe (although I am not sure) that this phenomenon may have started on this "France Has An Incredible Talent" show.
