Your reading is a possible interpretation of that statement, but I think the other reading is also possible and plausible: Luna was turned into Night Mare Moon by evil magic (from/as a separate entity), and that included both her physique as well as her personality.

Either way, rumour has it we're gonna get an episode about the early history of Equestria, so how exactly the transformation happened may yet be cleared up.
