I thought it all had to do with the points, and speed in completing the qualifier on Wednesday? The points make sure you qualify, and the speed decides where you are placed. If you finish all your matches first, you are the first slot on the tournament chart (top left). If you are the second to finish, the second slot (top right) and so on. To be honest, I have no source for this information other then a few weeks I've watched where my group ends up on the tournament board. If this is how it works, it isn't random but based on your performance in the qualifier. This also means that if the two top teams preform like the two top teams should, they would not face each other round one.
