No worries. The pilots receiving this brief and infrequent training will, of course, hardly, if ever, encounter the situation and will no doubt achieve and maintain the highest proficiency in the "simple tasks" of recognizing, diagnosing, and skillfully intervening for the potentially life-and-death condition. Onset to completion taking less time than asking "what is happening, it cannot possibly be happening, how did that happen ..."
Maybe someone should be working on an upset recovery guidance system that leads the crew safely through these "simple tasks". Creating such a system would not be trivial, but worth the effort.
