It looks like various magnitudes that you would find at 2 points along a
standing wave, with various fractions of the wave in the inductor as
frequency changes. In spite of hitting these various magnitude values,
there are still only two phases, 0 or 180 anywhere outside the coil. In
some cases, the standing wave goes through a node, inside the coil and
reverses phase from one end of the coil to the other.

Exactly! Now please explain how the nS delay through a coil
could possibly be measured using a signal that abruptly shifts
fixed phase by 180 degrees every 180 degrees.
