Barry was inspired by the identity of another hero that from his perspective was fictional, and in the context of his reality, he was the first "real" person to be called the Flash. So both he and Jay could definitely be called "the" Flash and the respective fastest men alive on their Earths. It's why things get flimsy when you factor in the Earth-1 versions of Superman, Batman, Robin and Wonder Woman vs. their Golden Age selves. Are they legacies of...themselves?
