It’s a tactical move. Since you only need 5 points you put all the teams that are most likely going to through to just advance. Put a smaller less likely team to go 3-0 and not risk losing points. Say that you put Fnatic to go 3-0 and they lose (which they did) then you won’t get any points for 3-0 pick or any points if they end up going 3-1 or 3-2. So It’s a tactical move just to get the 5 points needed from this stage.
