No, it simply means the parties can't sue each other ever again regarding the suit claims. That ship has sailed.

"A court may also enter judgment with prejudice, however. This signifies that the court has made an adjudication on the merits of the case and a final disposition, barring the plaintiff from bringing a new lawsuit based on the same subject. If a new lawsuit is brought, a defendant can properly invoke res judicata as a defense, because a court will not relitigate a matter that has been fully heard before."
