Something must have happened to the Zanpakuto when Kenpachi first held it, after looting it from a corpse, to make him believe, without a doubt, that it was in fact released. He wouldn't make a statement like that without something to back it up with.

Oh course he would. Zaraki makes off the wall comments all the time. He's not exactly the smartest, nor the most knowledgeable source we have, and furthermore, we know the sealed Zanpakutou takes on a personalized appearance as the Shinigami pours their reiatsu into the Asauchi. That was established by Nimaiya himself.
