Names matter. Whether they depict the same character or not is irrelevant. There used to be an exception to this if their JAPANESE names matched (EXP.ALL vs. Exp. Share), but as that required a reference due to the name change, that is no longer applicable. (And these two don't have the same Japanese name anyway, they differ in the exact same way as the English names do.)
It doesn't matter in this case anyway, since they're functionally different, as has already been mentioned. (So even if they DID have the same name, you couldn't use the old one in Standard.)
