Exim is clever. :-)

TFM contains this explanation:

     " ...the router may generate one or more new addresses (typically
     from alias, forward, or filter files). New addresses are fed back
     into this process from the top, but in order to avoid loops, a
     router ignores any address which has an identically-named ancestor
     that was processed by itself."
