It's probably in the rule book somewhere but I think I've seen it tweeted that if there is a 3 way tie where h2h does not secure the last team there are multiple criteria's that need to be met to determine a 4th and 5th seed and then the team with the better seeding gets map selection in a tiebreaker bo3
