The editinterface right allows users to edit pages in the Mediawiki namespace: that is, sitewide CSS and JS pages, and those that define the text that you see all around you.

If you're using the standard Wikia skin, scroll down. See the text "Around Wikia's Network"? That's actually modified by Mediawiki:oasis-spotlights-footer-title. You don't have the editinterface right but I do, so by editing that page I could change that text as it appeared on every page on this wiki - editing the interface.
