This is an unfortunate legacy issue. The original script used the page name for deciding whether to load the auto-refreshing code, this means for other languages, you'd need to add all the other language pagenames for the recent changes for example:

As so many people had already used the script, changing the way ajaxPages worked would have broken things for a lot of people. So, there is an alternate version of the script that uses the canonical special page name (found by viewing source of a special page and ctrl+f to find "wgCanonicalSpecialPageName"). This means it will work for recent changes (or other special pages listed in ajaxPages) on all languages, but you can only list special pages. To use this version of the script, put  in your global.js instead. I hope that helps! :)
