Then you were very lucky! If you have some slight asymetric in your system it might work like this. But if you would loose a prop with the other turning direction it would be even worse! There is no question if this is the case or not. It's physics and if you take a sheet of empty paper and think about the moments you get in an emergency case with five rotors, you will understand that this is not a stable situation. That's what DJI describes also in their manual.
