What's happening in this wiring diagram?

[rspst14]

Hey guys, can anyone explain to me what is going on in this wiring diagram:

http://www.seymourduncan.com/website/support/schematics/2hum_vol_tone_3way-w-ssp.html

My guitar has 1 volume, 1 tone, and a 3 way switch. I have two DPDT push/pull pots, and two 4-conductor Duncan humbuckers. I was thinking of wiring up some type of coil split or series wiring trick using the DPDT pots. I came across this schematic, but I'm really not sure what's going on here. I'd really appreciate it if someone could explain it to me. Thanks.

Re: What's happening in this wiring diagram?

When the switch is down, you have:

Parallel operation:
black/red connected to hot out
green/white connected to ground

Switch to middle (on-on-on only - ignore this position for DPDT operation)
single-coil operation:
black connected to hot
green/white/red connected to ground

Switch to top:
Ordinary humbucker operation:
black connected to hot
green connected to ground
red/white connected together

I hadn't really noticed it before, but to me, thats backwards. I believe I'ld
want "normal" operation with the push/pull pot "in". But easy to do - just reverse the wires on the switch.
