At this point, the number of remaining candidates equals the number of remaining seats, so the remaining candidates are declared elected.
In the end, 100%
of all cast ballots counted toward a winner.
This compares to 100%
if only the first-round votes were used.
You should be able to see that the winners have a more equal mandate in the final round than in the first round.
Note that even the "highest first-round votes" method is more democratic than most methods used in US public elections: the "vote for 5" method, which allows the largest block of voters to dominate, and the district method, where choices are restricted to the one or two viable candidates within geographical boundaries drawn by the politicians in office.
