I disagree with that. "Clyde said his brother killed himself and Chris believed it" is funnier than "Clyde's brother killed himself." And it makes more sense. Also, if you say things in-universe, you are kind of making the assumption that this is how Chris saw it.
And you don't exactly have to have autism or aspergers to fail to understand the joke. For example, after all the other absurd stories, I don't actually know if the wiki is being truthful when it says some of the more plausible-yet-ridiculous things such as that bit about Chris ending up at a fat black woman's house at the end of his massive road trip. Did that actually happen? More clarification would be great, and it's funnier to boot.
