No one is likely to fail a simulator check if they ONLY complete the items as per the FCOM, but then no one is likely to fail for applying extra precautions.
We should not be treating simulator exercises any differently to the way we would act in a real emergency. It appears that I am not alone in running a fire test after any fire drill.
But no, neither I nor other examiners I know REQUIRE it, because so far it has not found its way into the QRH.
Having said that, were you to dispute or belabour good advice you probably would do yourself no favours when the examiner graded the non technical skills section on your check form.
