Retractions share with original statements the attribute that they are in some cases made insincerely, in some cases for personal gain, and in others under duress.
That is, voters can help avoid the election of a less-preferred candidate by insincerely raising the position of a more-preferred candidate on their ballot.
If one feels the favoured candidate is certain to be elected in any case, insincerely ranking the second candidate first guarantees them a full vote if needed.
