I agree.Its an odd place for it to crack. Being a reputable LBS is all fine and well but we all make mistakes and maybe they clamped the frame rather than seat post? That sounds like the most plausible explanation as to how the frame has been damaged.
The stress on a frame is nearly all at the tube junctions, there is very little through the middle of the top tube.
