I believe he has been in this hobby for about 25+ years and was one the many I paid attention to when I began this hobby. Unfortunately most that are still in the hobby got tired of people who didn't understand telling them their tank would suffer because of their methods and they don't bother trying to educate people any longer. This is a sad thing because the most experienced people who have the most to offer are put off by the attitudes of those who need their experience the most.
I am surprised to see people scratching their heads here, this isn't new and there are plenty of examples of higher nutrient tanks thriving.
Big E's tank...po4 was tested at about .34-.37 and there is no question about the health, growth and color of his Acro's.

I don't want to detract from this thread but remember corals are highly adaptive creatures, in spite of what the books have led you to believe. The simple proof of that is the variability in everyone's tank and methods and the successes with each method. There is no cut and dried formula for success. I have seen more pale and sickly corals in the past few years then I ever did when I began keeping SPS.
