Not every BJJ school in the world, no. But in 4 years I've trained regularly at 3 different BJJ schools and every one showed an upkick from guard at some point or another.
And you're stating that as a matter of fact? Wow, I'm glad you can speak for every BJJ school out there. If you want to get technical then we can go back to the fact that Oleg wasn't trying to pass the guard at the time which was your counter point on the Fedor video. Hence there can be no guard pass failure.

Not only that but Vale Tudo schools and BJJ are actually not usually taught together and are usually found at odds from what I hear (Hugo Duarte, Marco ruas, Jose Landis Jon compared to BJJ such as Machado and Gracie).
