What is the T1 play off bracket in Americas league

So 6 teams qualify for play offs right?
Then why are there only 4 upper bracket slots? Do the bottom 2 start lower or did I miss something?

Pretty sure the bottom 2 will start lower like how they did in the NA challengers last year

Na top 2 get round 1 pass

Yes which means the bottom 4 teams mostly would be playing the first brackets while the top 2 teams would be straight away be placed in the Upper Semis I guess. Pretty much like the EMEA Challengers Playoffs last year if I'm right
