Photos from Minimbah are very interesting!

Two photos clearly show that it was the wing that was on fire, sooting the fuselage. Tyres are fine so absolutely no reason to keep pax on board in this case, and total luck that the fire crews happened to be there.
I need to repeat the earlier statement: You can not say that this was a good decision
because noone got hurt.
Keeping people in anything that burns is never a good idea. Best case scenario is that they get lucky because of circumstances (like wind direction), but mostly they are not that lucky. Be it boats, helis, airplanes, cars or houses. There is a reason you evacuate your house if the forest fire flames are touching your windows.
