They're alleging a trademark violation in his use of the name "Pirate Joe's" to sell Trader Joe's products, not that reselling them is itself illegal.

The case that went to the Supreme Court is unrelated to either Trader Joe's or this guy; the article is just juxtaposing it because it was also a case about international resale. But it was about someone importing international editions of textbooks for resale in the U.S., and the main arguments in the case turned on interpretation of a totally different area of law, copyright (so it's not really all that relevant here).
