I can tell you from personal experience, that this bug can occur and still able to retain the ability to move normally around the map. Though I have not seen any similarly reported case. It took me a little while to realize the consequences of staying, I disconnected very quickly when it did eventually dawn on me. I was to busy sight seeing to take advantage of the situation.
Yes, its true that in the vast majority of cases, that I am aware of, you will be unable to move.
