I'm not a compiler builder, but pass by referene has always meant, you access the parameter object directly. And of course,  the parameter mode does not (and must not) have any influence on the parameter passing method.
You can force pass by ref by adding access to the parameter.
In most cases, passing method is of no interest, compiler makes the correct choice. RM is silent on most types about this.
Tagged types and limited types are always PbR.
