I don't think that is true. Not a lawyer, but, WoTC can have a contract with the dealer/distributor/whomever, that they are not allowed to sell the cards until a specific date or until after a certain amount of time has passed. A couple of Years ago, Ford sued Jon Cena (some wrestlers guy - I guess he is famous) for having sold his Ford GT before he was allowed to. Cena sold the GT, and he was promptly sued by Ford. Cena ended up settling with Ford, probably because his lawyers told him he is going to lose and should just settle. In any case, just because a company sells a product, doesn't mean they lose all rights to that product. The dealer Cannon bought these cards from may be under a similar contract. Cannon has nothing to do with tat, so he i fine, but to say that once the cards were sold to the dealer, WoTC had no legal claims to them "at all" is not completely accurate.
