In Airbus speak, "latching" is a case whereby a failure degrades the flight control law to the point where it cannot regain a higher-level control law. AoA Protection law/mode can be exited as soon as the conditions which triggered it no longer apply.
EDIT : Therefore, because AoA Protection mode is triggered by a commanded condition rather than a systems failure (as in Alternate/Direct/Abnormal Attitude laws), it does not "latch" in that sense
