I have always assumed that the reason the monster teleports away afterwards is to provide a logical justification for the fact (which was true in Frog-knows days) that you can't get your item or gold back by killing the monster — the monster had supposedly taken time out to stash/sell/destroy the item before returning to the battle.
Now that monsters carry (or explicitly destroy) items and gold, the narrative justification is no longer required. So perhaps thieving monsters should stop teleporting away after every attempt?
