My guess is the seller has tried this with only one seat post; so the problem could be on the seat post rather than on the seat tube.
Other than that, it's possible the seat tube was reamed out only as far as seemed necessary at the time.
Bear in mind that seat posts come in a variety of lengths, so we're talking about half of an unkown number.
Whatever the problem is, I doubt it would prevent me from buying a frame I wanted.
