I read that also on Consumer Labs site. I've also seen that on another site but I don't recall which one. In any case, it's fairly easy to figure out how much calcium you get from fortified foods (at least for me). If I drink an 8 oz glass of fortified soy or almond milk I know I get the amt of calcium listed. Here is where your measuring cups and a scale are your best friends. When I first began using food sources for calcium. I measured out how much 8 oz would be in a particular glass I use (after that I just eyeball it). If I eat cheese, I'll use a scale to weigh 1 oz of cheese (which typically a serving/per calcium). But I do consider calcium from fortified foods as a supplement and tally that into my total calcium intake for the day.
