I think you may have misinterpreted. For your two required rotations, you will be provided housing. The location may be far from where you would be residing your first two years at NSUCOM, though you may request something closer if you have a hardship (ie, have a house, have children, wife, etc). You are not guaranteed to have those accommodations met.
Since you will be provided housing, it may not be adequate for you and your wife. You may be living in a one bedroom on a twin bed, in a trailer, in a dorm room, or whatever the accommodations are for that site. That may prohibit you from living with your spouse, but there is no clause that says your spouse can not come with you and you can make your own arrangements. I hope that clarifies things a bit.
