It certainly isn't that simple in a distributed network.
The currents into the end of a half-wave section are certainly
unbalanced at X and Y but the current amplitudes are pretty low.
5 watts into 5000 ohms is only about 30 mA. 1/4WL back at the
shorted matching section at ++,

Not that it ever does any good to try to get you to think about what
you are saying, but that is nonsense Cecil.

The short doesn't affect CM currents. The 1/4 wl line can act as
current step up if the far end is grounded.

Also, reach back in your rear and pull out another impedance number.
The impedance value you grabbed from there is for a very thin wire
compared to length, like an end-fed HF antenna. Tubing is alot lower on
the end Cecil OM.

Before going off on another Cecil-knows-best event and destroying a
thread to make it all about you, run the model. Six meters, yagi,
tubing. Not 40 meters and #16 wire.
