You answered your own question - if reflections toward the source are
eliminated in a Z0=50 ohm environment, the apparent (virtual)
impedance cannot be anything except 50 ohms. When you look at yourself
in the mirror, your reflected apparent (virtual) distance behind the
mirror is the same as your actual distance from the mirror. The
reflection is NOT where it appears to be, i.e. it is virtual.
