No, I think Nike meant that Special:AdvancedTranslate (or perhaps MediaWiki itself) assumes that one of the translated names must be the canonical/default one for that language, so if the configuration is different and doesn't respect this (as it seems to be if I understand correctly the excerpt provided by Nike) nothing works. If you tell Nike which one of  is the preferred translation he'll fix it.
