Street and house number are certainly two different things. It's more like series of movies (Die Hard 1, Die Hard 2, etc. are different movies but part of the same series. In the same way, a street could be seen as a series of houses or addresses. So the smallest unit is the house, then the street.

Yes, it's like a movie series. It's Die Hard 2. That's one name, not two, "2" and "Die Hard", but one: "Die Hard 2".

I didn't say it was two names, I said there are two different movies within the Die Hard series. Just like two different houses on the same street.

Yes, but each movie is a single entity and the number is part of that entity. Just like with "street+house number". It's one entity, not two.
