Zs can certainly affect the impedance looking back into the feedline.


I did that, and the SWR did not change. But, then you could say this was by
definition because the meter measured RL/Z0.


Chipman alludes to the problem not occurring with a resistive load
or with lossless lines. If the load is 50+j500 and the impedance
looking back into the lossy line is 50-j500, this seems to be
the correct conditions to cause the localized resonant energy
transfer problem.
