It's very easy to make one tiny, minor assumption to fill in an unknown that completely changes the context and consequently the answer - I've caught myself doing this a few times.As far as the legal responsibility for the debt goes with Subject To, my guess would be that the contract basically provides a pathway for the seller to pursue the buyer for recourse related to losses they suffer from the default of the original loan, like a form of indemnification, but does not absolve the seller of responsibility for the debt.
