Well, here we are further in the future. The guy who made the original video about bleach downfall retracted it, saying that he now understands that sj chapter orders do not represent popularity ranking.
He still makes the same points about the story structure with the arcs and now goes into the two aspects of fights scene (something I kinda wrote about in the flaming pit a few years ago).
Watch it if you still care enough to waste an hour.
