Yes, that was my assumption in this method. After C was eliminated those votes
supported B. But that meant only 45 votes for B, which was this time not enough
against the 55 votes of the A party.
The A party candidates were just like one combined "A1+A2" candidate in a
regular IRV election until that candidate won. After that there was a second
race between the candidates of the A party.
This approach clearly encourages formation of parties or other
groupings/coalitions. If all candidates are either under a left wing or right
wing coalition the bigger of those coalitions will win. (Hierarchies of
groupings/parties/coalitions are possible too.)
This approach also encourages parties to nominate more than one candidate, as
in the example where the A party won thanks to nominating a good compromise
candidate (A2, that had less first place popularity than A1) that appealed also
to the A2>B>A1 voters that would have voted for B (making B the winner) if A2
would not have been available.
