Hi Rob,

The latter, while clearer, is not really true.  Copeland always picks
the Condorcet winner, when there is a Condorcet winner.  Instances where
there is not a Condorcet winner are rare.  In those rare instances where
there is not a Condorcet winner, there's usually also a tie in the
Copeland result.
