SQL%FOUND and SQL%NOTFOUND

Question

Hi,
My friend asked me this question.
Why we hav these two attributes?SQL%FOUND and SQL%NOTFOUND
One will always be the opposite of the other.So one will suffice our need, no?
Thanks..

declare
     print varchar2(32);
begin
     delete
     from scott.emp
     where empno = 1000;
     if ( SQL%FOUND ) then
          print := 'found';
     else
          print := 'not_found';
     end if;
     if ( SQL%NOTFOUND ) then
          print := print||' and not_found';
     else
          print := print||' and found';
     end if;
     dbms_output.put_line(print);
     delete
     from scott.emp;
     if ( SQL%FOUND ) then
          print := 'found';
     else
          print := 'not_found';
     end if;
     if ( SQL%NOTFOUND ) then
          print := print||' and not_found';
     else
          print := print||' and found';
     end if;
     dbms_output.put_line(print);
     delete
     from scott.emp;
     if ( SQL%FOUND ) then
          print := 'found';
     else
          print := 'not_found';
     end if;
     if ( SQL%NOTFOUND ) then
          print := print||' and not_found';
     else
          print := print||' and found';
     end if;
     dbms_output.put_line(print);
     rollback;
end;
not_found and not_found
found and found
not_found and not_foundIt seesm that one is allways the opposite of the ather one. There are no exception.
