Induced signal?

In your alleged system, you carried RF through the coax and used the
coax as a swixcthing stub.

You seem to be confused by my actual system in my yard
Vs the hypothetical piece of coax I introduced as a
simplified example for discussion purposes.

Forget the coax example. In my yard, I have run two wires
up a piece of 1/4WL aluminum tubing to a relay which
switched a top hat in and out just as the other fellow
wanted to switch a wire in and out. The only thing that
I would have to add to turn that system into switchable
half-squares, like the other fellow has, would be two
3/4WL runs of wire. I suspect the SGC-230 autotuner at
the base would match the new feedpoint impedance just fine.
I've never seen an impedance it couldn't match.

In the other fellows system, he had a high impedance feed and had to
get a relay conductor past the high impedance feed without affecting
the system.

The two physical configurations being discussed are *identical*,
being 1/4WL of tubing through which two DC wires are routed.

They are TOTALLY different.

Once again, you make an outrageous exclusive statement
completely divorced from reality. If any one thing about
the two antennas is not different, your statement is
completely false. One wonders what compels you to make
such strange assertions.
