However, if you tug on it, there is a chance that it will not disconnect with a Lightning cable. There's still a good amount of force needed to actually pull and disconnect the cable. This means that if you, say, trip and fall, there's still a chance the cable will still be connected and limits the amount of distance the phone will travel.

With a Magsafe-like cable, it'll disconnect after the tugging happens, and if the pull from the tug is strong enough, it'll cause it to potentially go a greater distance, since there's no cable connected.
