And sometimes I see just one primary going down a road too. Just depends
on what the current loads and expected loads are. That's a good picture of
exactly what I was describing, very common here. Pole transformer
connected between one primary and the primary neutral.

Primary doesn't have a neutral.

One end of the primary connects to a live wire. What is the other end
connected to?
Another live wire that is 180 dergrees out of phase.

Aren't they talking about that single wire earth return? That
must be really
rare. I don't remember seeing it anywhere in my little world. EXCEPT
for electric
fencers to keep livestock in.
I believe it MAY still be in use in one of the western states of
the USA as well as a small portion of remote rural Saskatchewan, and
parts of the Australian outback - but it's use is declining steadily
even there. It WAS common in the rural electrification schemes of many
areas, but stray voltage issues with livestock, among other concerns,
has curtailed ot's use (voltage differential between water lines and
ground is a SERIOUS issue)
