Power in the load = forward power - reflected power.

Finally. You have seen the light.

Once you know the value of Pload, you can pick any pair of numbers
for Pfwd and Pref satisfying the above relation and you now KNOW
Pfwd and Pref. This is about as useful as the concept gets.

Toss it away.

Stick with Vfwd and Vref; they always work. There is no need for
caveats like 'sort of works when Z0 is mostly real'. And you
won't be misled into questions like 'where does the reflected
power go?' and 'how does reflected power fry the final?'
