On the other hand, knowing measured
S11 and the reference impedance for it, and the line characteristic
impedance, you can determine the SWR on that line.

That's true for a one-port load but not usually true for a two-port
impedance discontinuity in the transmission line.

This also brings up another point: do YOU define S11 to be the same
as reflection coefficient?

S11 is the (physical) reflection coefficient when a2 equals zero. When
a2 is not zero, the physical reflection coefficient, S11, will not usually
equal the measured reflection coefficient, the square root of Pref/Pfwd.
