Just like goku can get punched through 50 rocks and still get to his feet, tanks can get punched by Ifrit over and over again. Casting cure on someone is more like giving them a senzu bean than magical surgery.
The opening cinematic to a realm reborn shows this pretty well actually. The warrior is shown as basically being on his last legs, but there doesn't seem to be anything physically wrong with him. However the white mage cures him and he's ready to go again. Nothing is actually healed, but whatever internal store of something that protected and sustained him is back.
