My take - it's not so much about "low nutrient" as it is about "low leftover nutrients." If you put in nothing, then it's low nutrient, true, but also the corals have nothing to pull out of what gets put in. In your tank, untamed, you may feed heavy, but what's your NO3? I bet it's pretty low to negligible. So it may not be a "higher nutrient" system per se, it's just a system with a high throttle. High input -> high output.
I dunno, I could just be talking nonsense..
