I know the difference. it doesn't make any sense for there to be any sort of emphasis on the word it makes sense just fine. it's a goofy fun fact (i'm not big on fun facts, but some people are) and the fact that it was his brother is what makes it "fun" (slightly) i don't think it really needed emphasis but i think it's probably weirder to be taken aback or bothered by it being emphasized enough to point it out.
