If the starter is clicking then I would suggest the car is trying to crank it but it will not as you have a flat battery or missed of a cable or two, earth strap etc.
Yes. I think “checked” meant that he tried really hard to get it to slip and the engine always stalled.
It feels ok to me — better than it did before the clutch replacement — so I’m happier with it now than I have been since buying the vehicle...
