That's done in order to reduce the load on the server we call out to. 

While we happen to be connected after a successful callout, we try a
second RCPT with an address which is fairly sure to fail. If _that_ is
accepted, we assume that the server in question will accept _all_
callouts, so we don't bother to make any more (at least until the cache
expires).
