Well, in this incarnation of the game, Cave, and I to a lesser extent, are in charge of rulings.

But, in the traditional sense of the Hurt/Heal, double hurting/healing is being able to hurt twice OR heal twice in one turn.

At the moment, you have to perform one hurt and one heal. When Double Hurts/Heals are allowed, you're allowed to perform one hurt and one heal, OR two hurts, OR two heals.
