(1) A conditional
release order may relate to more than one sentence of detention, in which case
the order runs for as long as the offender would be liable to be detained
under either of the sentences if there were no conditional release order.
(2) The sentences may
include a sentence of detention previously imposed by the court that has not
been discharged and, if the person is released from that detention under a
previous conditional release order, the previous order is to be cancelled when
the later conditional release order is made.
