Why lucky?He was lucky that it completed safely, but anything could have happened.
Was that not the intended behaviour when using that App?

That's a plain vanilla operation for Litchi, not an anything can happen situation..It's good to know it returned to home when you requested it. i was talking to someone yesterday that used a 3rd party app automated flight. The drone lost contact but still flew the mission out of range. Took the required pictures with no contact and flew back. He was lucky that it completed safely, but anything could have happened.
If the radio disconnects from the drone it should return to home for safety. Some could argue that it should complete the mission, but the pilot need to be able to control it to stop an accident from happening.Why lucky?

Similar to the options normally available for loss-of-signal response (RTH, Hover, or Land), third party waypoint apps like Litchi offer an option to Continue with Mission upon loss of control signal. The default setting is usually set to Return-to-Home in both cases.If the radio disconnects from the drone it should return to home for safety. Some could argue that it should complete the mission, but the pilot need to be able to control it to stop an accident from happening.
Not necessarily, I believe that with some apps they are designed to carry out the programmed flight and then RTH. It's never interested me so I don't pay that much attention to waypoints but I do recollect someone saying that at least one app is designed that way and presumably writes the instructions into the drone's memory.If the radio disconnects from the drone it should return to home for safety.

I think you are incorrect about the gps/compass at start up. Gps does not provide orientation guidance when static, instead the compass gives the IMU a directional reference. Once airborne, the IMU uses that to provide heading orientation with the compass secondary. The need for calibration comes from anomalous values generated by local interference, ie nearby metal. There was never a need to recalibrate in a new location and certainly not before each flight.@hedbonker the issue you mentioned about moving 100 miles away ,was primarily a compass related thing ,and had nothing to do with the actual homepoint directly
with todays drones, if on start up the drone senses an anomily, between what the satellite information and the compass seem to be saying,then you will get a compass calibration required warning on the screen
what can happen sometimes ,is that the drone has been launched, before enough satellites have been locked , and at some point away from the take off point ,the satellite lock is established,then that point will be where the drone will return to
the two messages saying homepoint is set ,once on the ground ,and then as the drone takes off, are just to make sure, that the operator has got the message,the second one is a comfirmation of the first, the homepoint remaines the same
as far as a homepoint mission is concerned ,then realistically once the drone has located its compass heading and position by GPS coordinates ,then it should realise that the stored waypoint mission coordinates, and the actual coordinates ,are not the same ,and maybe abort the mission from taking place, whether this is the case or not i do not know ,just summising
maybe someone can try this out and see if it is the case
There was never a need to recalibrate in a new location and certainly not before each flight.
