I think the encryption thing was more about Facebook not being able to intercept your messages, read/store them, and remain unnoticed. Of course they can "still" read your messages as they could rewrite the app in a few subtle ways to achieve that easily, but that's nothing new. I guess that if the app starts looking for the chats within the devices, it would be much easier to spot than it would if the messages were just analyzed as they went through WhatsApp's servers (so that's what the encryption is for).
