Especially because it gives me the sneaking suspicion they were made as such to support releasing USM as two versions instead of a single third version like other gens. Gen 5 made some sense because BW2 were sequels and meant you could be B & B2 or W & W2 to get a full story and set of main legends. There's been no similar real gameplay reasons shown so far to support USM being two versions instead of one.
Though I suppose, upon thinking about it, they're really no more lazy than the Kyurem forms.
