I guess I should clarify: Begin with S being the set of all candidates. 
At each step, if there's a Condorcet winner among the candidates in S, 
elect him. Let S_C be the solid/acquiescing coalition with the most 
support that's not already been examined. If S intersect S_C is 
non-empty, let S equal S_C. In any case mark S_C as examined, then repeat.

In other words, the "current set" that's to be checked for a CW limited 
to its members is the set that's the result of all the prior 
intersections, not the currently greatest-support unexamined coalition set.
