This means that the system is matched and thus the re-reflected
voltage equals the reflected voltage.

No! NO! NO! The voltage re-reflected from any physical impedance
discontinuity equals the reflected voltage times the physical reflection
coefficient. That is the S-parameter term s22(a2). s22 is the physical
reflection coefficient. a2 is the reflected voltage incident upon port 2.

If the reflected voltage is 70.7V and the physical voltage reflection
coefficient is 0.5, then the re-reflected voltage is 35.35V. This is
all explained in HP's AN 95-1 on S-parameter analysis.
