It's an amusing phrase, and it's not entirely true (especially in endgame content), but it's pretty much spot on for a level 28 dungeon. Focus on healing the tank, and if something kills you (i.e.: the tank can't keep aggro on everything), it's the tank's fault.
You didn't mention if the tank was a gladiator or marauder. Warriors (and to a lesser degree marauders) tend to have lower resists, and ultimately make up for it by having lots of HP. At lower levels, though, you'll often see them losing huge chunks of HP, and you'll have to focus more on healing them.
One last tip: As a healer, I do spend time doing damage in dungeons, but I don't sweat it if I can't. It's far more important to have enough MP to heal than it is to add a little bit of damage. When I do cast damage spells, I focus on spells with lower MP costs and alternate effects. Stone, for instance, is better than Stone II in a dungeon because it costs less MP and it adds a heavy effect, even though it does less damage.
