Can some Swain main confirm if Beatrice does double damage to Daisy?

I just noticed that she does double damage to the Maiden. Which is kind of BS for Yorick, because since you can't move the bitch out of range, QE one shots her.

But I'm not sure if it does work on Daisy? It seems the same, but Swain's Q does double damage to minions(as opposed to monsters and pets), and Yorick's summons are sometimes treated as minions while Daisy is always treated as a pet, so it might not. So I'm not sure if I should keep banning Ivern.
