Answering (with a human voice!) the correct time zone for the wrong "London" is about the mildest possible bug you'll ever see. I might not even call it a "bug". Let's call it a mild inconvenience of modern life! The aspect that's ruffling feathers, I believe, is that it's one of those cases where someone might have reasonably assumed something was built one way 'under the hood', and was confronted with an effect which forced them to see that it was not implemented that way at all. The issue isn't the 'bug'. It's the realization that their mental model was wrong. Specifically, something has a name ("Siri") which might lead one to believe that everything from that manufacturer using that name refers to the same thing. (Isn't that the point of a name?) Clearly, it's not. Your hypothesis sounds plausible, so I tested it. I have a Mac laptop, which has the same 'Location Services' that iOS has (AFAIK). I asked Mac Siri what time it is in London, and got a response for the one in England (further away from me). So that doesn't explain it, or at least not all of it.
