If you handed it to a clerk, and he/she did not say anything to you about the box, I think it should have kept on going and not been returned to you.
Yes, I went to the PO and handed it to a clerk, who weighed it, stamped it and took my money... I went back to the same clerk when it was returned and she said if she would have noticed she would have told me about this policy/rule. She really is a nice woman, and I believe her.
EDIT***** When I reused the Priority box, I had to wrap it in brown paper to cover up the stamps and labels that were all over the top and bottom of it. So it was not easy to see the Priority stamped on the box itself.
