In my understanding, the way this works, is that there is a protein in dry beans that serve as a protection against the bean being eaten by animals, so that it can remain a seed and grow more beans. When the bean is soaked, and begins to sprout, that protein is activated, and it is undigestable to animals, who learn don't eat that thing. By providing an enzyme that either converts starch to sugar, or by fermentation (converting sugar to alcohol), that protein can be pre-digested, to make it digestable by humans.
