Did you swap x and y in the second last sentence and really mean

No, a properly calibrated Bird wattmeter will measure
some reflected power to the left of y but zero
reflected power to the left of x.
You clearly have never calibrated a Bird Wattmeter for a 450 Ohm Line
(or any line).
As for this "some" power. "Some" power can be "measured" by any of a
half dozen ways to improperly use instrumentation. It doesn't lift
the gravitas of a "hint" to proof.
Hint: Point x achieves

This must be the 80% of correct that is moot.
