You are either confused about what I said (or deliberately

Bottom line: At points '+' in the example before any
cutting, either reflections exist or they don't.

If reflections exist, there has to exist an impedance
discontinuity to cause the reflections. There is no
impedance discontinuity.

If reflections don't exist, there is nothing to change
the direction of the flowing energy. Therefore, energy
is flowing both ways through the '+' points. The *NET*
energy flow is zero. But it is easily proven that
energy is flowing from one SGCL to the other.
