Twitter didn't have retweets originally, they introduced a retweet feature in 2009. The "RT @twitterhandle" form started as a convention among users a year or two earlier. Twitter may have implemented their APIs in a backwards-compatible way by presenting their later implementation of retweet as such to older clients, though I'm pretty sure their internal representation of a retweet would be different.
