Although it happened on takeoff, they were at about 1000ft, so it's not an immediate "do or die" moment. They should have been trained to calmly identify the failed engine before feathering it. Many high-time pilots say that the first thing you should do when an engine fails in cruise flight is absolutely nothing. You need to relax and calmly assess the situation. Although they weren't in cruise, they certainly had enough altitude to be able to take 10 seconds to calm down and properly identify the problem.
