Nopey. It is nothing like figure #7.
>Diagram B looks like something you would see in a Knob & Tube installation.
That could be.
>I've also heard it called a "California 3 way."
No, I think the [Chicago/California/French/etc] three-way is the one with the switched neutral.
I hereby retract my earlier comment that about a Code violation.
I have flattened out the diagram into four parallel lines (one runs only half way). Except for the fact that four wires are required rather than three, it has no problems that I can see.
I wish I could post my redrawing of it.
