I think i have finally seen the confusion point. you can not at the

use s parameters or other steady state reflection parameters or
impedances...

Someone said it a long time ago: You can't have your cake and eat it
too.

One cannot be using the reflected wave to establish a dynamic virtual
short while, at the same time, the virtual short is causing a dynamic
re-reflection of the reflected wave.

The virtual impedance is (Vfor+Vref)/(Ifor+Iref) but if that is the
impedance doing the re-reflection of that same Vref and Iref, then it
cannot also be being used to establish the dynamic virtual impedance,
i.e. if a virtual impedance is re-reflecting all of the reflected
energy, it will necessarily disappear from existence because there is
no longer a Vref and Iref to cause it to exist.
