MAX , I agree that the auto ignition on this engines makes a difference , this could very well be the reason , good point.
Departures and arrivals will most likely put the engines in a more vulnerable condition for flameouts due to maneuvering at slow flight speeds combined with changing compressor speeds . This may also be part of the equation for them to mention Ignition ON when WX dictates during this flight phases.

I have never yet experience a real engine flame out .
My eng out cases on jet aircrafts have been oil seal related events. ( 4 )
There is no question in my mind that Ignition will remain ON after a relight if the WX/ash conditions creating the flameout persist !! Even maybe if they are no longer present , it would really depend I guess .
Thank you both , hope to hear more inputs for this speciffic Airbus topic.
