You're missing the point, Roy. It indeed does function the
same way in both cases but if there are reflections present,
your lumped circuit analysis rules are known to fail.Your
analysis of both cases may be equally wrong in both
cases.

What is the traveling wave current delay through the coil in
degrees? That's easy to measure. That current delay is the
degrees that the coil supplies to the antenna. You can ignore
any measurements involving standing wave current as being
essentially meaningless. What is important is the traveling-
wave current delay through the coil. Please measure it and
report what it is for your 'physically small toroid'.

Your lumped circuit analysis pre-assumes a zero delay
through the coil. That delay is certainly not zero in the real
world.
