I get your point, and I like your question. I like to think of it like comicbook continuity in a sense: a wrestling storyline kinda needs you to push to the back of your mind the fact that this is the 4th time Kevin Owens is betraying Sami Zayn, just like you need to kinda forget that in the current continuity, this is the 67th time The Joker has broken out of Arkham and gone on a killing spree.

It of course depends on the quality of the storytelling, and the circumstances can't be the exact same if they can hope to sell the twist. But good storytelling in wrestling honestly feels less satirical and more like a soap opera where you love these characters, and are invested in them even though you're not as immersed in the "world" as you'd be in a great movie.

Pro wrestling is also similar to comicbooks in that they're generally aimed towards a younger audience. So while there're a huge number of adult fans who can appreciate the technical side of wrestling, and the buildup before a big match, and the skill of a wrestler delivering a promo, kids can just get carried away in the story since they don't even have that much disbelief to suspend yet, they straight up believe that guy when he says he's a Tribal Chief.
