I think it's because Brazil has the only Win in Group G, two others have Draws, and Korea has the only Lose.
So Brazil is In already for the next round. ( Others will know better ) I'm not the Greatest when is comes to Soccer.
I also think that their 2-1 win over Korea wasn't that great.....A lot thought it would be a 3-0 win or More. Ivory Coast is a Much better team than Korea.
Just my 2 cents
BOL ! with whatever you do.
