Section 4.6.5 says:

     bool lost_assert(S,G,I) {
       if ( RPF_interface(S) == I ) {
          return FALSE
       } else {
          return ( AssertWinner(S,G,I) != NULL AND
                   AssertWinner(S,G,I) != me  AND
                   (AssertWinnerMetric(S,G,I) is better
                      than spt_assert_metric(S,I) )
       }
     }

It should say:

     bool lost_assert(S,G,I) {
       if ( RPF_interface(S) == I ) {
          return FALSE
       } else {
          return ( AssertWinner(S,G,I) != NULL AND
                   AssertWinner(S,G,I) != me  AND
                   AssertWinnerMetric(S,G,I) is better
                      than spt_assert_metric(S,I) )
       }
     }

Notes:

Excessive parenthesis before 'AssertWinnerMetric(S,G,I)'.
