I can't answer why on your first question, but on this one:
The RM in section 6.2 specifies how parameter passing is done based on the type.

http://www.ada-auth.org/standards/12rm/html/RM-6-2.html#I3382

Based on that, your limited private which is really an integer would still be
a by-copy-type.  I don't know the RM's intention but the wording suggests that
at least.  Note you can also used the "aliased" keyword in a function/procedure
signature to enforce an aliased variable which will be passed by reference
as well:

-- Object is passed by reference
procedure Do_Something(Object : aliased in out Some_Type);
