I'm not certain what you're not understanding.
If they had 8 season tickets, then it's possible they got 16 total. The maximum amount of extra tickets allowed was 8, regardless of priority points. I thought I laid that out pretty obviously in my post, but perhaps not. If this helps make it easier, we'll call season tickets X, so X+8=max # of tickets. Like I said, I have 10 season tickets, I got my 8 extra, thus, 18 tickets. Nobody got more than 8 from the additional requests. I know plenty of people/businesses that have 30+ season tickets, QB club members, the works, and again, their max was 8.
