I thought this meant the official adjustments like Jebbin said, that have been floating around the internet and now are in the latest expansion. However, for the Board Game Arena implementation, it means that if you get a random faction, you start with 20 points, and if you decide to flip to the other side of that same color, you get 15 points. I can't imagine anyone wants to play by this unofficial variant, and it might be a bug.
