I find the term off-healer extremely misleading and using it to "teach" newcomers about their job isn't a very smart choice.
On the other hand it can be quite helpful to designate certain responsibilities. Whether you call it "off-healer" or "pheasant-plucker" is irrelevant. There truly are situations where one healer (or even specifically one player) is better suited to meeting the party healing requirement, taking care of one or both tanks, DPSing specific targets, or any combination of the above. This can also change from one phase to the next.

In your average DF activity where fine distinctions are unnecessary, then I'd fall back on the sort of etiquette you described.
