I agree that it is pretty dodgy since they are using rule 40.13 which states - "If the race ends whilst the safety car is deployed it will enter the pit-lane at the end of the last lap and the cars will take the chequered flag as normal without overtaking."
It seems the drivers got the message that the safety car was coming in on that final lap before the end of the lap and not that the race would finish under safety car.
