Is it possible to repent after death in Catholicism?

In the following quote from the Catechism, it seems to imply that you can repent of a mortal sin after death. How does that fit with the standard "Once damned always damned after death" view that the Catholic church teaches elsewhere? > Suicide > > 2280 Everyone is responsible for his life before God who has given it > to him. It is God who remains the sovereign Master of life. We are > obliged to accept life gratefully and preserve it for his honor and > the salvation of our souls. We are stewards, not owners, of the life > God has entrusted to us. It is not ours to dispose of. > > 2281 Suicide contradicts the natural inclination of the human being to > preserve and perpetuate his life. It is gravely contrary to the just > love of self. It likewise offends love of neighbor because it unjustly > breaks the ties of solidarity with family, nation, and other human > societies to which we continue to have obligations. Suicide is > contrary to love for the living God. > > 2282 If suicide is committed with the intention of setting an example, > especially to the young, it also takes on the gravity of scandal. > Voluntary co-operation in suicide is contrary to the moral law. > > Grave psychological disturbances, anguish, or grave fear of hardship, > suffering, or torture can diminish the responsibility of the one > committing suicide. > > **2283 We should not despair of the eternal salvation of persons who > have taken their own lives. By ways known to him alone, God can > provide the opportunity for salutary repentance. The Church prays for > persons who have taken their own lives.** I'm curious about the phrase "salutary repentance". Does this mean that someone in Hell can repent?
