It has been a few years since I was at a bank that had an active Dealer Paper program BUT - the best I remember the FTC Notice referrs to a part of the "Holder in Due Course" concept and is to protect the bank from being held to any warranty requirements that the dealer / original creditor may have.
I think the statement was part of the standard retail installment sales contract / note that the dealer completed.
