Just for clarification, in-combat healing isn't a monster thing. But if a monster escapes from an encounter and takes a short rest, they can spend whatever healing surges they have at the end of that rest, just as PCs can.
Well once they've exited combat, they're off camera, so whatever means they have (or don't have) of healing isn't any of the player's business, be it surges, a MacGuffin, or bandages of monster healing.
At that point, the nebulous 'Monsters still don't use PC rules for nuffin' kicks in and whatever is best for the game at that time is what happens to their hit points.
