I think it would be like this:

-Group 1-
Seed 1------\___Seed 1------\
unseeded---/........................\____Seed 1
......................................... /
unseeded---\___ Seed 2------/
Seed 2------/

-Group 2-
Seed 1------\___Seed 1------\
unseeded---/........................\____Seed 1
......................................... /
unseeded---\___ Seed 2------/
Seed 2------/

And both Seed 1's would then play each other? I don't think you face anyone from the East Side if you're West side until the finals. Am I right?
