I think if you look at the ruling you'll see that Wood was seeking relief on the runoff election, which hasn't occurred yet (or not completely at least). Most of this document is explaining why Wood lacks standing. This is not an ad hoc legal move as cases are frequently dismissed for standing.
His complaint is that proceeding as-is will cause himself undue harm as a person of a disadvantaged class of voter (i.e., one who is not breaking the law). The judge reminds him that no one has a right to commit voter fraud and that he is speculating as to whether the fraud he's alleging will even occur. Thus, he's also speculating as to his future legal injury and his claim does not satisfy the second of four criteria given (on page 4) for issuance of a temporary restraining order; therefore the judge does not have to consider his complaints based on the merits (criterion #1).
