It seemed kind of weird to me, too. LBS checked the bike out, then removed the seatpost and took a picture showing that it extended several inches below the crack. Their email with photos of the crack, and of the post length, were all it took to get me a new frame. I'm not sure if that's Cervelo or LBS, but LBS said they had never seen a frame crack in that location before. They said that repeated impacts, even small ones, are bad, though.
I was very happy to have it replaced, though.
