Yup. It measures the reflection coefficient of whatever impedance is
connected to the port on the opposite side from the transmitter.

No, it doesn't.

It measures the MAGNITUDE of the reflection coefficient. It discards
the information which is contained in the phase angle of the
reflection coefficient.

Sorry, I left that important word out.


To be picky, in most implementations, its response is a function of
the forward or reflected power provided that Zo is real, and the
magnitude of the complex reflection coefficient can be calculated from
those measurements.
