It was my thoughts only not what is in practice,I am reflecting what happens in NFL.
Ie.
Top seeds always have home advantage from any knock out stage so if you are number 3 seed and that is top seed left you have home advantage.
Just as 5 6 7 8.could be left after QF stage.
And I believe 1 plays 8 not 5 which 4 plays.
Im on about semi finals. If 1 plays 8 and sf would be vs winner of 5v4.
If 5 beat 4 then it'd be 1v5 with 5 being at home although much other scenarios too
