The drawing doesn't make much sense to me.

The biggest code violation is the dimmer is in the neutral. You can't
switch the neutral.

Also the fan will run all the time.

Also I don't know how you get 90V from black to black. You should get
240V on one and 0V on the other.

He is also marking a hot leg black on one end and white on the other.

It is a puzzle alright. It is not an electrical circuit.

Maybe it's not the best drawing in the world, but it shows what's there
accurately.

The 90 volts is on account of the dimmer, which apparently doesn't allow
the full 120 to get through.

The black and white wire markings are what exist. I know they're wrong;
that's the whole point. (I didn't do this wiring; I only came to install
a device in the box. Not my fault.)

Personally, I like Vista, but I probably won't use it. I like it
because it generates considerable business for me in consulting and
upgrades. As long as there is hardware and software out there that
doesn't work, I stay in business. Incidentally, my company motto is
"If this stuff worked, you wouldn't need me".
