You're incorrect. You can look it up on the wiki if you want, and I'm sure there are plenty of people with replays if you still don't believe it.
I had one just a few days ago where a lavaloonion raid destroyed my CC (which had a few loons that were still in there). They dropped their heros for cleanup, no troops came out. I log in, loons are still there, which is exactly what is supposed to happen.
