I think the first one is the way Apple used to sell academic versions - it was the same for Final Cut. They changed their policy a few years back and decided to only offer a 10% academic discount. On that basis they couldn't fairly enforce the no upgrade policy anymore.
It may be that you're not allowed to use an academic version for commercial purposes (most software companies make that provision) but I'm not even sure Apple could tell, even if they cared. When I bought an Academic version of Final Cut last year they gave me the same box but just took 10% off the price.
