NEC ECC: Accepted Programme with un-agreed CE duration's within it

Following on from you response, am I correct then in saying that if the PM accepts a programme (cl32) with a planned completion 1 wk after the Completion date due to the notified CE (unaccepted) of a 2wks duration, the Completion Date is unchanged.

And when the PM assesses the notified CE at 1wk duration, planned Completion will be the same as the completion date thus no change to the project Completion date.
