The way I see it, the current flows from one conductor to
the other? So
what's the neutral for? The only thing I can think of is
perhaps these
devices have several independent parts in them and some of
those parts
are 120 volts...

Trolling? Well; for example: Cooking stoves. The various ones we've
had (three or four countries) vary somewhat.
And only in 3 wire plus ground North American - Mexico 115 - 0 - 115
volt wiring practice.

Buy typically our present cooking stove has 230 volt elements and 230
volt oven heater/broiler etc. But the timer clock on this current one
is (IIRC) I115 volt.
Also there is a 115 volt light bulb in the oven controlled by a switch
on the stove and a 115 volt 'convenience' outlet.
Can't remember on this stove if that outlet is controlled by the
timer; but sometimes they are. And it occasioanally makes a convenient
place to plug in something heavy like a 1500 watt electric kettle or
fry pan.
On the other hand our 230 volt electric hot water heater does NOT need
a neutral for anything I can think of.
