Yes.  They could have avoided that by using the somewhat more simple 
method that James-Green Armytage named "Benham" in his "Condorcet-Hare 
Hybrids" paper:

He describes three other methods in his paper, but they are all more 
complicated without any justification.

I think this method would be usually easier to operate than the 
Condorcet//Hare method they suggest, and generally less clunky.
