So the next question is: What is the phase change

It just occurred to me that you and I may be talking
about two different phases.

---Z01---+---Z02---

Vfor1--|--Vfor2

Vref1--|--Vref2

Continuing: What is the phase shift between Vfor1 and
Vfor2 for example:
(1) a capacitor with -j567 ohms impedance
(2) a 600 to 100 ohm dual-Z0 stub
(3) a single 600 ohm stub

I hope you are not going to tell us it's the same in
each case.
