This is rather puzzling, a repair stand does seem like the culprit, but someone would have to doing it really, really wrong to produce dents like this it seems.
Anybody who would clamp a vintage bike by the seat tube wouldn't have the intelligence to clamp it correctly.
I wonder if the clamp was setup for a seatpost and the doofus didn't adjust it for the frame
