(1) This section applies if—
(a) the board decides to suspend or cancel an offender's periodic detention; and
(b) when the suspension or cancellation takes effect, the offender is also subject to periodic detention under another sentence of imprisonment—
(i) whether concurrent or consecutive with the period suspended or cancelled; and
(ii) whether for the same or another offence.
(2) To remove any doubt, at the inquiry for the suspension or cancellation under this part, the board may also exercise its powers under this part in relation to the other periodic detention.
