What you have stated is absolutely correct. In normal and alternate law as long as stick is out of neutral it is a constant load factor demand. Without the flare mode you will have to flare and neutralise the stick, flare and neutralise the stick. Which is not a good way to land. Flare mode allows continuous back pressure as the auto trim stops and aircraft starts pitching down. This mode not being available in alternate law, a direct stick to elevator relationship is given as flare mode where aircraft pitches down as the thrust is reduced. Direct law causes concern as it is described as the lowest form of flight control laws( other than mechanical back up) but when you look at it as another flare mode to help you land it doesn't look so bad. In fact landing in alternate law will be an ordeal.
