The Special:Nearby feature seems to support changing the language. nearbywiki.org is just English while the OP has a language switch but it's limited.
Now I'm not sure if switching the language pulls in more results or just changes the article language...
When you change the language you are essentially moving to a different Wikipedia site, so yes it does - it pulls the results from the local site you are on.
