The few pages that are "Code Name (Real Name)" are only like that to help the page when it comes to Google searches. "Spider-Man (Peter Parker)" gets 12.3 million results while "Peter Parker (Earth-616)" gets less than 200,000. Those "redundant" redirects exist for housekeeping purposes - sorting appearances, quotes, etc.
