I once submitted a very minor bug fix update for one of my apps. It ended up 'In Review' for 3 weeks for no obvious reason. After a week I asked if there was a problem and got a form reply saying it was still 'In Review'. Eventually it got approved just fine. I can only think the reviewer went on holiday during the review...
I wouldn't be surprised if rejecting a binary that had already been approved dumps you onto a different track with more extensive review. They're just going to have to wait this out.
