What cause a jet engine to "flame out"?

When a jet engine is deprived of an oxidiser they shoot a flame at the back. It seems counterintuitive to me because shouldn't this prevent combustion from occurring? Could someone please explain this to me?

Lack of fuel or air,(oxidizer) can cause a “flame out”. Which essentially is when combustion ceases. A lack of air, (oxidizer), can cause a “rich” fuel air ratio, allowing unused fuel to exit the tail pipe which can cause a visible flame.
