Activating score manager without attribute grants score to whom?

Score manager:

score_manager_device<public> := class<concrete><final>(creative_device_base):

has two functions to grant score:

  1.  # Grants points.
     Activate<public>():void = external {}
    
  2. # Grant points to `Agent`.
     Activate<public>(Agent:agent):void = external {}
    

So if the second function grants score to agent, who gets the score from the first function?

I suppose that to everybody
