Not quite, not everything is false, not everything is true. I've been using Litchi for almost 7 years now and the missions are fully autonomous on all older drones, Phantom, Inspire, Serie Mavic, Mavic 2... In case of signal loss the option is either to revert to the point of departure, or to continue the mission (which I always do). The drone can be 2 miles away without a link with me, it continues its mission and I resume the link when it returns.
However with newer drones like the Mavic Mini 1, Mini 2, Mini SE, Mavic Air 2 and Air 2S cannot continue the mission if the signal is lost, in this case they are not able to continue waypoint missions beyond signal range .They make a return home.
But however the mission is automatic without the sticks. You can use the sticks during the mission, depending on the flight programming to steer laterally the drone or to speed up or slow down the drone, that's all, it doesn't stop the mission.
