Not the way that I am reading. That is only for normal reroutes...not for situations beyond the company's control.

A rerouted regular pilot who is not scheduled to release within four hours of the
scheduled release of the last duty period of his original rotation, or within the same
calendar day of the last duty period of his original rotation, whichever is later, (the “time
limitation”) will receive single pay and credit (or the applicable pay, no credit for a GS,
GSWC, IA or IAWC) for the rotation as flown, plus half pay no credit for any duty
period(s) that extends beyond such time limitation.
Exception one: If such rerouted pilot is not scheduled to release at his base within such
time limitation due to a circumstance over which the Company does not have control
(e.g., pilot’s origin or destination airport closed, weather on pilot’s routing, mechanical
on pilot’s assigned aircraft) he will receive only single pay and credit (or the applicable
pay, no credit for a GS, GSWC, IA or IAWC) for the rotation as flown.
Exception two: The time limitation will be 30 hours for an international category pilot
when rerouted into, or while in, trans-oceanic operations.
Exception three: A rerouted pilot who is scheduled to be released at his base beyond the
time limitation will not be entitled to premium pay if he is again rerouted for the purpose
of releasing him at his base within the time limitation
