Old editor didn't. I'm guessing this is the way it's parsed with the edit button. MediaWiki keeps the url /wiki/Redirectname when it redirects, but you edit the real page unless you click back to the real redirect page. Looks like the new editor just recognises the URL you're at atm, and edits that page (which is the redirect)
