Indeed... personally I see this as the main reason to fly in ATTI mode. So you know what to do and how to control it when it decides to go into ATTI mode on its own, which mine does fairly often. In ATTI it doesn't hold its horizontal position and will keep going in whatever direction momentum or the wind is carrying it. I think this is the cause of a lot of crashes when folks don't know what to do when it goes all ATTI on its own.A good idea to practice with it also in case you ever lose GPS during a flight & have to pilot back manually.
