You obviously don't understand how this works. The combination of antenna
and feedline presents a certain impedance at the end of the feedline.
What
the tuner does is transform the 50 Ohm on the TX side to the impedance on
the feedline. And when this all matches, there is no SWR. Neither on the
TX
side of the tuner, nor on the feedline side.

Wann bet? :)

Try it some time. Tune the tuner so there is no SWR at the
transmitter. Then place the SWR meter between the tuner and the
transmission line. You will still see the same SWR that you started
with!

Of course you will. That's because you put the SWR meter on a place where
the impedance is not 50 Ohm anymore. So now you have a mismatch between the
feedline and 50 Ohm directional coupler in the SWR meter.
