Lucky,
I wonder if you aren't confusing the issue. Unless I miss my guess, Brunswick is obfuscating on the drillings of this ball. I think the PSA marker, or whatever Brunswick is calling that point, is just the rest of the world's Mass Bias point for the core. Remember when resins were introduced and everyone called it "reactive resin" EXCEPT BRUNSWICK, who had to call it "reactive urethane". It confused people so much, that some people were sayign they preferred reactive urethane over reactive resin and they wanted other companies to make their balls of reactive urethane, instead of resin, WHEN THEY WERE ONE AND THE SAME CHEMICAL ENTITY!
Treat that marker as one does an MB point, as the fine tuning normally done by the positioning of the CG. The line represented by pin-CG-MB is the core's asymmetry; the core angle is basically the angle in degrees that people reference, which together with the pin distance, governs a lot of the ball's path.
