Unless I'm misreading this, no copies are made.  You are simply passing along the dummy arguments to a routine whose explicit interface is known, so it would just pass the same item by reference.  RECURSIVE allows local variables to be distinct, but I don't see any in this excerpt.  It would also ensure correct behavior for any locally created descriptors or pointers.
