Big difference is that the fire in the China 737 was in the cabin and not in the cockpit!
Once again, if you have a fire and smoke in the cockpit, you do not sit around and wait for 90 seconds! You get out via the cockpit windows or the cockpit door. Imaging the chaos in the little galley there is hardly any space for 2 or 3 crewmembers.
Furthermore, if there is a fire in the cockpit - where all the controls are- there is a big chance that a) there are no hydraulics, B) there are no electrics for the alternate flaps, c) the flap lever console interface to servos's is interrupted by the fire or shorcut citcuit. Furthermore the PA system could be u/s aswell.
Our OM-A says that only when conditions permit, the captain will leave via the rear pax door. If you had to exit trough the cockpit windows I would say this would clasify as a justification for not being able to do so...
Looking at the picture and seeing the firhehoze nozzle harpoon of the fire truck penetrating the cockpit only confirms the severe fire/smoke condition in the cockpit.
