It is the expected behavior because all the Metaclasses are subclasses of
Class. If you look at Class' hierarchy you'll see

Object()
  Behavior()
    ClassDescription()
      Class
        [ ... all the Metaclasses ... ]

and when looking at Class class hierarchy

Object()
  Behavior()
    ClassDescription()
      Class()
        Object class()
          Behavior class()
            ClassDescription class()
              Class class()

It's a little weird yes.
