From the first video, people are standing up and the plane is still rolling down the runway. As the crew goes through the checklist the plane comes to a stop, the speed brakes are retracted and when the engine is shutdown the fire goes out. It looks like the fire was caused by the liberated blade striking an air-oil cooler in the coldstream. There is no fire warning protection in this area.
The evacuation was announced after the engine was shut down.
