They are not equivalent because the anonymous access opens more possibilities (example below), but you are certainly aware of that.
So I guess you have another question in mind...

with C1, C2;

procedure test is
  x2 : C2.Inst;
  type My_Reference_1 is access all C1.Inst'Class;
  r1 : My_Reference_1;
begin
  x2.PB (r1);
  x2.PA (r1);
  --  ^ expected type "Class" defined at c1.ads:3
  --    found type "My_Reference_1" defined at line 6
end;
