Warhol started out in advertising, actually. It was how he paid the bills before his pop art "broke". Here's a link about a show that will be displaying his commercial art. I'd kill to go see it - I've always loved his shoe drawings.

Intent is important, but there's a point where the artist's intent becomes secondary to the audience's interpretation - and there are multiple audiences as well, which makes for complications. What I see here, though, is more a juxtaposition which is something that can happen in a gallery as well as on the street - the whole point of a curated show is to create a larger conversation out of a number of individual works. Film festivals, as I mentioned upthread, often do the same thing. It's just part of the deal. In any case, once a work is out of your hands, it's going to exist in a larger context and that context will give nuance to or even subvert you intention.
