There is no impedance discontinuity - therefore no
reflections.

You are still making the same mistake as you have from
the beginning. There is a discontinuity at the source.
In your example, it is called the load-line. The load-
line in the previous example is source voltage divided
by zero, i.e. infinity. That's what the reflected wave
sees.

But the load line is the same for the generator equipped
with a circulator so it too must reflect the wave. If this is
the case, what heats the circulator load resistor?

I notice you skipped the tougher questions related to a
transmission line that is 3/8 wavelength long? Is there a
zero to divide by in this case? Apply analysis equally
to Experiment A and B.
