From same article, "As great as that sound, the Victus is not invincible, and bits of dirt and metal inside your pocket and handbag could still lead to a scratch"... so if you are trying to avoid scratches that would irritate you, like myself, then that' why you'd still use a protector. JerryRiggs video also shows in his scratch test that the new glass really didn't improve much in scratch level.
Also, even though they say the new glass can withstand a higher drop, remember those stats are their standard stats based on test from a flat piece of glass flush against a test phone's frame with a thickness not mentioned in article. We don't know if Samsung used a thinner spec glass to save weight and more importantly, when you bend the glass like Samsung has with the curved edges, the rating is out the window because you weaken the glass when you bend it and the glass is now more "proud" meaning it sticks out beyond the frame exposing itself to more direct contact if dropped.
Always glad to hear when your phone is using the latest and greatest and hope it helps your phone get a better chance of surviving the next time you drop it. But it's not that huge a step where you can toss using a case or that breaks still wont happen at 3 feet with an unlucky drop.
