What is sprouted bread?

Here's a link to read that breaks it down: http://www.foodforlife.com/what-are-sprouted-grain-breads.htm

TL;DR: the grains are soaked in water until they sprout, then they are drained and ground up to be made into bread.

I don't get how it can be lower glycemic than regular bread. The sprouting activates the amylases in the grain which start to break down complex carbohydrates (starches) into simpler carbohydrates (the sugars maltose and glucose). How is having more simple sugar lower GI? May taste good, but very dubious about any magic health claims.
