There were two positions remaining, and one of them had to be male. From the description, I think everyone had 2 votes and one had to be for a man, so if votes were split evenly and no one voted for both men, the men would each get 50% and the three women would get 33%. A real vote isn’t going to be perfectly split, but it puts the neutral expectation for the male candidates much higher than the women. If the men went head to head and then there was a separate vote with the second place and the women, there wouldn’t be the same bias.
Note that this is from January, so this was even before the gestapo went into overdrive with refusing to show warrants or identifications.
