With some comments here on the forum, someone will take it seriously. So no, stopping with two ice axes is possible only in action movies. When the slope is so steep that two ice axes are needed, only the rope or the valley stops you in the fall. That's why one ice axe is used on easier climbs, to self-arrest in case of a slip - use the pick. The pick at chest height (not 1m above the head, like some do) is stabbed into the snow with full body weight. Other techniques only for sci-fi movies.
