This is an example of a creditor sneaking in a contract to renew the statute of limitations for purposes of obligating a consumer to pay on a time barred debt. Please read carefully and be aware when running into offers disguised as establishing new credit!
A consumer has every right to pay on past debt if they want, that is out side of the statute of limitations, and in the deal establish a new credit account, but if you default on this second account you will have a new statute of limitations, that can give the creditor remedy to sue you in court.
