A company I worked for did that. Not really for geo-location reasons, but brand ones. People that worked for foobar got a @foobar address, and barfoo people got @barfoo. It was all owned by the same company, but the companies that got bought up kept their brands alive, and this was part of it.

I bounced around divisions, so I kept getting new logins. The old emails would forward to the new ones, but the logins would be sunsetted out as I no longer needed access to old projects. I actually don't know how the backend works, other than every time I need some permissions or something fixed, invariable the IT people get very confused by the mess, whatever it is.
