Humbucker Coil Splitting question

[BesaMoogie]

Hi, I am currently installing a new set of Pickups (Irongear UK) and I want to try the coilsplitting option. Looking at the diagram the company provides, I would like to know, which coil is active in the split mode? I heard, that in the Neck position the south coil (the one with the crews closer to the guitar neck) is preferred. I provided a wiring diagram.

Thanks

Grounding the green/white junction as shown in the diagram with the push/pull pots will leave the screw coil active. Same for both neck and bridge pickups.
