You might want to look again; yes all the tape entries end in commas,
till you hit the last one, and that ends in a semi-colon.  So in theory
you could have all the tape drives listed enabled.  Think of the comma
as a delimiter (which it is) for the list of tapes, and the semi-colon
denotes the termination of the list.
