Generously - specifying Croydon does help travellers figure out where they need to be more specifically than just London. I'd like to hope if they met in New York City it'd say e.g. "New York - Riverdale" or something rather than leaving you to guess where in the city exactly.

Most things "in" London aren't in the centre unless they're tourist destinations or they're extremely old. The most surprising thing I ran into right in the centre was the International Maritime Organisation's headquarters, which is right on the Thames because historically that makes sense in a way that arguably it already didn't when that was built, and certainly not today.
