This is related to exact this one single torque sensor?!

Yes, exactly.

Is the cadence shown correctly, if the motor stops?

I won’t be able to test this on the bike today, but I just ran a test on the bench — with enough load so that the cadence would at least show up on the display.
I did a simple experiment: I tried to spin the wheel evenly at about 10 km/h and watched the cadence readings — they stayed around 80 rpm. Given my drivetrain, the readings matched pretty closely with what the drivetrain calculator showed.
What I found a bit strange is that after stopping, the cadence doesn’t drop to zero right away — it keeps showing the last value for a while. If you pedal backward during that time, the cadence is still calculated.

You can check the cadence sensor signals with two voltmeters and see if there is something weird
