Neither; It works as designed.In other words, the fire suppression system either has big design error or a serious documentation problem.
The purpose is to contain a fire in the engine compartment for long enough for the bus to be evacuated, and for the fire department to arrive on scene.
That it subsequently catches fire is not a failure to achieve that design brief.
It is, however, the reason why our procedures state that under no circumstances should anyone return to a bus once it has been evacuated, without approval from the attending fire crew.
That's also the reason it's called a "suppression" system, not an "extinguisher".
