That's what you get when you use the surge impedance and compute
surge rho. Try steady state impedance for steady state rho.

rho = (0-50)/(0+50) = -1 as expected

Heh, heh, the steady state impedances are V/I ratios which are results
incapable of causing anything. Your logic is a closed loop. The V/I ratios
cause the rho to be -1. Therefore, rho=-1 causes the appropriate V/I ratios.
Can you name any other result in reality that causes itself? Hint: Only
physical impedance discontinuities can cause reflections. Image impedances
are incapable of causing anything since they are an end result.
