It is not non sense. I am spaniard myself and I did not understood what he was talking about until I saw the correction(is this a club name or something?).
If I want to talk about "Seattle" and use "Siadol" a lot of people are not going to understand.
A name is what something is called. For people it's rude to call them by a name they didn't choose but for non-persons that doesn't matter, if everybody else wants to call it "Siadol" then that is its name.
