Are we then supposed to infer that it [the source] doesn't re-reflect
the wave if anything other than a short or open circuit appears there?

To that list of two, we can add two more. If the source end of a
transmission line is terminated in a pure reactance, it re-reflects
the reflected wave.

When 100% wave cancellation of reflected waves occurs at the source
due to total destructive interference, it re-reflects the reflected
wave energy components as constructive interference energy in the
opposite direction. Anything else would violate the conservation
of energy principle.
