Yes, that's why you need a directional voltmeter or directional
wattmeter to separate the forward wave from the reflected wave
when reflections exist.

When I do this on a D-cell, what are these two voltages?

Reflected voltage is zero during DC steady-state.

It would seem that this belief will lead to some serious decidability
issues.

If standing waves exist, there is one forward wave component and one
reflected wave component. If standing waves do not exist, there is
no reflected wave component. Shirley, you can tell whether standing
waves exist or not so you will know whether you are dealing with one
or two waves.

And don't ever trust your voltmeter again.

Do you use a DC voltmeter to measure AC? Do you use a 60HZ AC voltmeter
to measure 1 GHz RF voltages? Do you use a 100MHz o'scope to look at
a light wave?

If reflections exist and you are using a non-directional voltmeter, you
will read the NET voltage. USE THE APPROPRIATE MEASURING INSTRUMENTS!
