I think i have finally seen the confusion point. you can not at the
same time talk about reflected waves and re-reflected waves and also
use s parameters or other steady state reflection parameters or
impedances... this means you can not talk about individual reflections
from the stub connection point without also analyzing the traveling
wave inside the stub, nor can you track and sum up all the reflections
using the steady state impedance of the stub as if it were a lumped
value. to do so violates the conditions where the s parameters and
reflection coefficients are valid, the sinusoidal steady state realm.
