There is no impedance discontinuity - therefore no
reflections.

You are still making the same mistake as you have from
the beginning. There is a discontinuity at the source.
In your example, it is called the load-line. The load-
line in the previous example is source voltage divided
by zero, i.e. infinity. That's what the reflected wave
sees.

It is definitely best to recognize that when the source impedance
is equal to the line impedance, there is no reflection at the
source.

You have been asserting that since your first posting and it
is a *FALSE STATEMENT* as proved by the latest example.
