Interestingly after the 5th match was complete, the game decided I had not qualified. On the last match I smashed Olympiakos 6-0 and SLB lost to barca 3-0. Unless I am missing something this must be a bug?
Also goal difference counts on the H2H if you are tied to be very careful not to attack too much if you are one down to a team of similar ability because it could kill you. I've gone out of Europe twice because of this H2H goal difference. It's a manager's worst nightmare.
