If a trigger doesn't have an event, does a defeault event occur?

I saw this trigger on several other maps my friend found fun
so i was confused when there was no event, so i was wondering if there is like a default event that occurs on

Defeat Quitting Player
    Events
    Conditions
        ((Player((Integer A))) slot status) Not equal to Is playing
        isPlaying[(Integer A)] Equal to True
    Actions
        Unit Group - Pick every unit in (Units owned by (Player((Integer A)))) and do (Unit - Explode (Picked unit))
        Game - Defeat (Player((Integer A))) with the message: You have been defea...
        Set isPlaying[(Integer A)] = False
        Trigger - Run Victory <gen> (checking conditions)

The trigger is activated by using the

Trigger - Run Defeat Quitting Player <gen> (checking conditions)

or by the

Trigger - Run Melee Initialization <gen> (ignoring conditions)

in other triggers.

In other words, one of these actions is used in another trigger to activate this trigger.

it could also be an added event but almost the same thing.
