The after-game meeting point refers to the after-game gathering location. This is optional for the game creators.

When the after-game meeting point is turned on and when the game will be over because of the time limit or having all tasks completed, the app guides the players to the meeting point. 

When the after-game meeting point is not assigned, then the game is merely finishing when the time will be over or the last task is completed and the players are not guided to any meeting point.
