Those are script-land events. Currently all events generated by core code (typically the analyzers) are defined in events.bif. You can see in the SSH scripts where those events are generated.
The reason you're seeing a false positive is because the SSH successful login code uses a heuristic to guess if the login was successful or not and sometimes it's wrong.

That information is encrypted in SSH.
