Chinese whispers through the FA grapevine is that the CPT didn't order an evacuation because he was concerned about pax being evacuated into burning spilt fuel.
I don't have enough information about this incident to know if his concern and decision not to evacuate were justified or not, but it should be noted that in an evacuation, airport RFF will protect the slides as a priority.
