Actually she does have dialogue on a genocide route as well, if you come to Snowdin before clearing the forest. The same goes for some NPCs in town. Some act as usual, some make small references to the fact that "today doesn't seem safe", some disappear. Everybody disappears only AFTER you finish killing everybody in the forest. It is understandable that it's somewhat hard to discover, because most players either don't go back and accidentally abort the genocide route, or don't go to Snowdin before clearing the forest first, because they want to get a little extra XP from mini-bosses, or because they're afraid that even visiting Snowdin before clearing the forest aborts the route, which is not the case.
