I'm not sure I understood what the problem is, but can't you simply test on the keys with the same varname? i.e.:
  if (defined $hash{$key}{$key}) {
    # do your thing
  }

Would that work? I used defined in this case because the value might be null, and that's not really what you're testing for, is it? You might still have the two levels assigned even if they do have a null value.

Spank me if I'm wrong...
