I heard the same thing Greg. Apparently when Kien tried to run just pellets and carbon he would still get a fairly significant PO4 reading (Hanna checker). He concluded that bioPellets alone were not stripping PO4 fast enough so he runs GFO religiously. No more Po4 issues.
Every tank is different tho. I know plenty of people running pellets without any PO4 issues as well.. But then again I also know people who don't apply anything additional to just water changes. Grrrrrr! This hobby can be so annoying!
