Staring into the abyss
It is just a dumb argument - made dumber by the fact that you have still picked an arbitrary goal post that undermines your essential argument by suggesting there could be two. But "ultimately", there was only one challenger who successfully challenged in the end. Therefore, "ultimately" the only realistic challenger to a grand final is the eventual grand final winner. There, fixed. Still a dumb argument though.
That interpretation is just asking for trouble
