Such arrogance ...
As long as I can get an idea of the competence of the person I'm sitting alongside, then frankly anything goes.
You are not required to assess competence on a revalidation "Training Flight" - IT IS NOT A TEST!
I will usually chuck in an emergency or two, but I'll generally do that on any flight.
If you did that to me without briefing or my agreement on my "Training Flight", I'd land and offload you ... and without any payment!
The 1 hour training flight has no guidance other than the single statement in LASORS, a very different thing from anything an AME will do.
LASORS is not authoritative - we have already established that.

PS Incidentally, I think the AME analogy is absolutely valid ...
