It's not that unexpected, because you do recurrent training in the simulator every 6 months. And there is a set of emergencies that is done every time, for example engine failure / fire during takeoff must be done.

All pilots are trained to know the immediate actions required for a whole set of scenarios (we call these memory items) the point of the sim check is not to learn them but to check that you know all of them and to keep some recent experience. Because these things happen so rarely in real flights.

I've had for example only once had an engine failure after takeoff and it was a partial failure without fire. In the simulator I think I've done it at least 100 times and most times they put it on fire for good measure so you're in a hurry to get on the ground. The real world one was very uneventful, return to the airport, taxi back, do a lot of paperwork.
