Isn't it true that for lines that have a length
that is any multiple of a quarter wave,
the phase shift when matched is the same as when mismatched?

Otherwise, (1) is correct AFAIK.

Another point or two and then I'll shut up.

1)  The expected phase shift in a line is only achieved when the line is matched.

Quarter wavelength lines have the magical property that the output current is equal to the input voltage divided by the line Zo.  So with multiple inputs tied together, and obviously having the same voltage, the output currents will be equal.
