But does that rule apply during liftoff or only when it's in-flight? Based on the map it probably never got that much altitude, as it barely traveled 2*length_of_runway, and that's including the runway itself.

Any time after it’s too late to abort takeoff.
Pilots should be able to “regain full control of the aeroplane without attaining a dangerous flight condition in the event of a sudden and complete failure of the critical engine…at each take-off flap setting at the lowest speed recommended for initial steady climb with all engines operating after takeoff…” [1].
