It doesn't say Apple can prevent the resale, it says the buyer is not entitled to the educational pricing if they are buying the machine for the purpose of resale. The fraud is for the student to buy a machine under the pretext of using it himself, knowing full well that he is buying it for resale. I'm sure it's either in, or incorporated by reference, that text that people don't read about accepting conditions of a sale. In practice, Apple can't afford to sue every weasely kid who thinks he's entitled to free money for being clever. So they also restrict it to one computer a year and take their losses on the young criminal masterminds.
