i'm an arborist by profession.
Even modern high quality chains break from time to time. either from misuse, accident or material fault. on average a chain snaps on me every one to two years. luckily modern chainsaws have a chain catcher under the clutch so even when a chain should snap it will immediately arrest on the catcher as it leaves the bar on the underside and be stopped at the catcher immediately - if you are lucky - just dropping down from the catcher harmlessly or slapping the hand guard on the rear grip where it will lose its momentum.
in the worst of cases one of the chain links will get caught and the rest of the chain will come whipping around on the underside of the bar - miss the hand guard and slap the underside of your rear arm, upper leg or your hip if you are holding the saw sideways.
in any case its going to be like a 35mph whip with teeth but it wont keep running and actually be pulled through your flesh as it hits you. wounds from this should be superficial due to the chain loosing most of its energy on the catch.

should you ever pick up a saw with this safety feature missing or damaged, do not use it!
