I know it's easy to be an armchair critic, but every time I've had my drone struggling against a headwind the first thing I've done is switch to sports mode and bring it down as low as practical, in a forwards glide path. I notice the video carefully crops out the altitude and distance readouts (something to hide?), but it certainly looked like there was plenty of scope for dropping lower (eg at 1:51). Also, if pushing the last out of a battery I automatically start picking out sensible emergency landing spots to bail out on (eg somewhere accessible next to an easy to find landmark, smooth ground, away from long grass, water or other things that would make recovery difficult).
Also his theory about flying backwards to follow a downwards glide path isn't quite grasping the drone specs, aerodynamics and how wind affects the drone. The mini 3 has less available tilt in reverse (35deg vs 40deg forward) and hence less available forward thrust. This undoubtedly translates into a poorer ability to make headway into the wind if going backwards. The body is also at a slight angle to the props so it is more aerodynamic in forward flight (props pitched forward, body relatively neutral pitch). If caught out by the wind the best bet is to drop low and fly forwards in sports mode. If running low on battery or making no headway then scan around for an emergency landing spot.
