That article suggests the final name element is that of the parent, which I'm inclined to agree with, but it could equally well be a family or clan name.
On Orc names that don't fit the convention - there are a number of names in MW that don't fit the usual conventions for that NPCs race, and I think most of them are either oversights (e.g NPCs added by devs not aware of the convention other devs were using) or obscure in-jokes.
