My sheet agrees with yours for the samples I checked.

Here's an example that changes nothing but allows
isolation of the component energy flows.

It appears to me that the confusion arises from
the *series* resistor.

It seems to me that this circuit is quite different.
There is a reflection where the left TL connects
to the 50 ohm resistor. There is a reflection when
the reflected wave on the left TL arrives back at the
source and there is a reflection when the reflected
wave on the right TL hits the 50 ohm resistor.

This circuit takes an infinitely long time to settle.
The previous circuit only had a reflection at the load
and settled after one round trip.

Quite different.
