It really is an amazing ability--it's like for any question she's got two answers on either side of the fence, but said in different ways. And I doubt she's really thought that out and is doing it on purpose, it just comes out. So it's like, "It's not about sex at all, it's about love..." but then Dumbledore becomes a-sexual. He doesn't stop loving--that's actually Snape, I'd say, who's more about shutting himself off from love because he's the nasty one. Dumbledore seems on the contrary to be all about love, or at least acting as if he loves and wanting to inspire love in others. He's still claiming his problem is that he loves too much in OotP when he claims that's why he kept secrets from Harry. (Snape, meanwhile, is bitterly saying that love is for fools. And that works because it's really Snape who's able to be manipulated by his love for someone else. Dumbledore just knows how to pretend to be a loving person to manipulate others.) That's sort of a tangent, but basically yes, I'm seeing the same contradiction here. It's like once the right thing gets said you can go on and demonstrate the exact opposite and maybe nobody will notice.
