Since it lists the name of the band before the CD's release date, I can only assume that when it says "Office Of Strategic Influence" it refers to the band itself, and by listing it's members, past and present, would include Mike Portnoy as he drummed on the band's first two albums.
I honestly do not think Mike is on OSI4 - he would've said something by now, considering the number of projects/bands/albums he's done this year, this would've been the one to make the most fuss about had he been on it. He's on OSI4 as much as he's on Storm Corrosion - meaning not at all.
