(I think)
I assume that's a mistake - which is common on Duncan diagrams now - since it would obviously be far better to swap the coil-split wires from both pickups so it gives the split neck in the neck position, not the split bridge.
There's another, in my opinion better, scheme too - wire it as if it's a standard Telecaster 3-way, with the switch rotors to the pickups and the four switched terminals to the volume pot. Then connect the two unused terminals at each end to the 'opposite' humbucker coil splits - this gives:
Bridge humbucker
Bridge humbucker + split neck
Both humbuckers
Neck humbucker + split bridge
Neck humbucker
- which is more logical to use.

Neck parallel

...fer instance. Though I think you have to turn one pickup around to do that.
@ICBM - so to correct the mistake on the diagram, would I basically just need to swap the red and white wires from the humbuckers to where they're soldered on the switch? You're right that it's more sensible to have split neck at the neck position and this is what I'd like.
Should that then result in:
1 - Bridge HB
2 - Both HB
3 - Neck HB
4 - Both Split
5 - Neck Split
If I'm remembering correctly about the colour coding on Duncans, that should also result in the neck-side coil of the pickups being active when split, ie the screw coil of the neck pickup and the slug coil of the bridge pickup - which is both hum-cancelling, and closer in tone to a Tele middle position than if the bridge is also split to the screw coil.

The only advantage of the circuit is that it offers Bridge + Neck from a basic five-way switch rather than a Superswitch.
ICBM's wiring suggestion resembles the modern PRS Custom circuit.
Sporky's suggestion is easily achieved with a 2502N selector switch. Its PCB tracks handle all of the fancy coil permutations.
I was hoping to find more ideas out there - but stumbled on the same 2 SD diagrams, which aren't a lot of help if they are wrong anyway.
To somebody well-versed in following guitar wiring illustrations, this inconsistency is surmountable. To the average noob, it is extremely unhelpful.

Neck + split bridge
Neck + full bridge

Using a standard 5-way. It was for a single coil at the neck, but a single-conductor humbucker would be effectively the same.
I'll see if I can find it, if that sounds like what you want.

Standard CRL switch, if you number the terminals like this:
1 2 3 4
5 6 7 8
(< neck bridge >)
Then:
1 to volume control
2 and 3 to bridge pickup hot
4 and 8 to neck pickup hot
5 to ground
6 to bridge pickup split
7 no connection (this can also be connected to terminal 1 for extra reliability, but is unnecessary)
It's slightly complicated in that the coil of the bridge pickup which is active in position 2 is the opposite one from position 4, so you may have to reverse the wiring of the bridge pickup to get the coils you want active in both positions, and the middle 'both pickups' sound has the neck pickup connected to the split of the bridge, not the hot - this works well with a single coil in the neck, but might be less good with a humbucker.

You guys have been super helpful as usual and I've just completed wiring up my HH pickguard today. Thank you all who assisted above!
I used this diagram in case anyone finds it useful in the future. Basically gives you split pickup configs without the need for a push switch or mega switch. Also uses bridge "inner coil" (IC) instead of outer coil that a lot of split diagrams use. I'm very happy with the results.
Only thing I've had to sacrifice is both humbuckers together, but I prefer two singles together anyway.
Wire colours above are the same as on Seymour Duncan diagrams except white on SD diagrams is light blue above.
One day I'll put the treble bleed cap on there. But that's a whole different can of worms that I'm not ready to open yet
Using the bridge inner and neck outer coils also makes the middle position hum-cancelling.
