So its just an anti reflective laminate??
There's some kind of chemically hard baked outer coating on top of the laminate that is used to get it up to that 98% mark (in conjunction with the laminate). This is the part they have trademarked/patented so the sales rep was hesitant to go into details (or he simply didn't know).
From the website which is vague as well as to the coating itself:
"Pilkington OptiView™ is a laminated glass with low reflective coatings on surfaces #1 and #4 (both outer surfaces of the laminated glass), which reduces interior and exterior visible light reflectance to less than 2%. As a consequence, views from both inside and out are clear, un-obscured and virtually reflection-free."
EDIT: Adding the actual website url might help...
