3 P90's - follow up question

OK, all you beautiful helpful people, on Oct 21st I asked a question about a wiring diagram for a guitar with three P90's and two toggle switches, where the first toggle would switch between the bridge and neck pickup, and the second toggle related to the middle pickup and gave off / in-phase / out-of-phase.

This arrangement is like the Yamaha SA503TVL which has 3 volume controls and 1 tone: I wanted a simpler layout.

Now forget the simpler control layout for a minute, I'd like to ask a specific question about the Yamaha and that second toggle, and how it manages to reverse the phase of the middle P90 (or DOES it?).

The evidence that says it can reverse the phase on the middle pickup is shown in the links below - ESPECIALLY the YouTube link.

Meanwhile the nice people at Yamaha have supplied me with a schematic / circuit diagram, here: QUESTION from reading the diagram do you agree that the 2nd toggle can switch the middle pickup between in-phase and out-of-phase?

Here's the evidence of reversed phase:
