I think there aren't any different. I can't write anything in any language.
Two of us have tested and been able to paste in your script above, so it's hard to know what the issue is. It could be cacheing, either at your end or on the server, or it could be that you are using a proxy - if that is so, please tell us. Anyway, if cacheing was involved it will have timed out now, so please try again, making sure that the links are active (i.e. only translate the bit the user sees).
By the way, you shouldn't need to rtl tag now, as the whole page has been set to rtl. We are testing a Mediawiki update that will mean they are not needed at all very soon.
