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.

This circuit has a reflection at the 50 ohm resistor because the impedance transitions from 50 ohms to 100 ohms, then back to 50 ohms.
