Having the assumption that energy does

see between reflection points, if we disallow energy passage
at zero voltage points.

The medium at the zero voltage point is homogeneous.
Nobody has produced a reference for or example of
reflections occurring in a homogeneous medium. Until
such evidence is introduced, it is probably safe to
assume that reflections in a homogeneous medium in
the real world are impossible (except in a human
mind where anything is possible).
