The way I've always seen it, the Nemesis rule is less about representing anything in particular in-universe and more about representing overall comic book narrative. I don't have a thematic justification for why Voss should be unusually good at punching Tempest, but I do know that heroes fighting their nemeses should be big and dramatic, which is represented in-game by a) making it have a bigger impact, and b) providing a bonus to encourage players to make it happen more often.Similarly, the Operative and Chairman turning on each other should be a much bigger and more dramatic event than one of them fighting one of their underlings or something, so the Nemesis rule says hey, this is a big thing, it has a big impact and you players should try and make it happen. Similarly, heroes attacking each other will always be a major event, but Legacy striking Young Legacy really ought to be more important than Legacy striking Ra - and so the Nemesis rule says it is.
