Publishing status in move_base

Hi everyone
In exercise 4.4 I’m trying to ‘cheat’ my robot by sending a GoalStatusArray message to the topic /move_base/status with the value ‘3’ (succeeded) the state variable get the value 9 (lost), but, what I dont really understand is why the robot continues moving to its three goals…¿is that because while the robot reachs these goals it doesnt pay attention to the status?
I don’t really understand how the navigation stack works in this case.
Thanks in advance!!
