Does MonoDevelop Autocomplete Event Listeners?

So, today I stumbled across a functionality in MonoDevelop that seems extremely useful, but I'm not sure if it's actually doing what I think it's doing.

I use event handlers a lot. I almost always format the class dispatching the event like this

 public class EventDispatcher : MonoBehaviour {
     public delegate void MouseOverNotifier(GameObject e);
     public event MouseOverNotifier MouseOver;
 
     void OnMouseOver () {
             if (MouseOver != null)
                 MouseOver (this.gameObject);
         }
 }

and format the listener like this

 public class EventListener : MonoBehaviour{
     private GameObject s;
 
         void Start(){
          s.GetComponent<EventDispatcher>().MouseOver += Listener;
         {
 
 
     void Listener(GameObject g){
         //g is being hovered, do something...
     }
 }

But today I noticed that when I get to actually attaching the listener, if I bring up the autocomplete window after the += I get something that says appears to automatically set up a class with the event dispatcher name, and the specific event, preceded by the word "Handle." It then automatically creates a function below with the same name. So for the above example it would have automatically generated something called "HandleSMouseOver" after the += and then create a function by the same name, ready to put code into, with the correct data type in the parentheses and everything.

Sorry, sort of a long description, but is MonoDevelop doing what I think it's doing and just doing a bunch of extra formatting work for me? I couldn't find any references to this behavior anywhere.
