What does is lead do?
I'm trying to learn about administering AEM, and I got to the point were I was just trying to create user and groups. May I know what does this checkbox does?

And if anyone know how to make a hierarchy, that would be great!

That's a left-over from the old MCM module (iirc introduced with CQ 5.5); It's never been of real use and can safely be ignored.
(and btw the classic UI dialogs you are using and going to be deprecated ... in 2019 I would prefer Touch :-))
HTH,
