Thats the next step if Obama and Holder refuse or fail to comply with the federal court order. Its the only genuine enforcement option available.

It ought to be done before the executive can ignore the order — that way the ignoring of the order itself can be cause for Treason.
If it's held out until after, a defense could be made that they weren't actually being invaded when the order was ignored — IOW, declaring a state of invasion (and acting on it) would preempt this defense altogether.
