They array outputs and sets the first actor of class you specified.
I’m guessing (because I don’t know) it gets them in order they were place in the world (when you place them in the world the 2nd and every next gets a number next to it) so you are always getting the first one you have placed in the world.
It won’t matter which one you’re overlapping in this case, it will always get and set the first one you placed in world.
I posted some info below because I wanted to try to do it myself. Take a look and if you have any questions just let me know. There is a video at the bottom showing how it functions.
