Has all previous shows been covered in there?

I'm honestly struggling to understand the strategy behind this. Many bands do these kind of things, but post the videos a day after the respective concert. What's the point of putting these out two or three weeks later when even more shows have taken place in-between?
It's not like it's too hard to do one minute video within one or two hours...
