Official sources deny it, from Wikipedia Aeroflot 1492:
The information that evacuation was delayed because some passengers grabbed their baggage have not been confirmed. According to TASS's law enforcement source the majority of passengers in the tail end of the aircraft had practically no chance of rescue. "This is evidenced by the position of the bodies of many passengers who were found in the tail of the aircraft. They did not even have time to unfasten their seat belts, they died of poisoning in their seats. Someone might have lost consciousness when the plane hit the runway. The causes of death of all the victims are now established" - said the source. He added that the passengers from the tail section of the aircraft, who managed to escape, moved to the front of the aircraft even before it stopped.[10] According to witnesses some baggage fell from overhead compartments during the hard landing and passengers removed them in order to free the passage.[11]
