Actually I've always interpreted this differently: Scrapper Champion and all the other cards with arts that had bios on the website but weren't legendary creatures (there were a few actually) DID show these legendaries as part of a world-building effort, but since they understandably shy away from having too many legendaries (and especially ones with smaller effects) in a set after what happened with Kamigawa the compromise was that the art does show the people the bios talk about, but the cards only show their general occupation or role. I don't think that it has anything to do with being misleading.
Oh yeah, they do this a lot, whether it be semi-important characters who just don't get a card (Jenrik) or totally unimportant characters who get names for the purpose of story articles on the website. The story articles leading into New Phyrexia basically alternated between important characters and cannon fodder.
