Exactly, you may find it just as secured as when you packed it. Other times...not so much. It depends entirely on the TSO opening it.
You might want to try something other than a box. I've seen a good amount of plastic tubs come through baggage and they seem to hold up better than a cardboard box. They're also less likely to roll and get stuck in places.
