You can clearly see fire in the engine area as as the aircraft touched down. I think a big part of the PIC's decision not to evacuate rested on the fact that fire services were already standing by when the aircraft landed. 2 minutes is a long time to wait for fire trucks to respond when your engine catches fire on the ground.
But in this case, the fire trucks were already there when the aircraft landed, and provided the crew with excellent information. I think the PIC made the right call. Professionalism through and through.
