I don't think that is how it works. I always thought that Barry and his friends don't exist in Kara's world. Supergirl just has the adventures of characters in the Superman-mythos and Martian-mythos.

They just listed a few specific names that didn't exist on both names, but they both still have Central City, Corto Maltese, and other DC things, so why not a random minor villain like Mr. Bones? I think it would be neat.
