Ahhh, but you didn't bold the "up to," did you? I can read the first sentence to imply that once they are done selling season tickets by the end of August, they will look at how many remaining seats they have. If they have enough for all the folks that renewed by the deadline to purchase 4, great. If not, maybe they allow only 2 per renewal. So they are indeed allowing you to purchase up to 4. I know, that's a stretch, but really - let's see what happens before we imply the athletic department is deceiving us.
