I don't think that Weiss sings the other songs just because the same artist that provides the singing voice sings the other songs. Are two characters in two completely separate series the same person just because they have the same voice actor? I don't see how this should be different.

Casey Lee Williams provided Weiss' voice for Mirror Mirror, and just happens to sing various other songs for the series. That is all, doesn't mean that weiss is the same person as whoever sang those other things in-universe.
