I actually somewhat found an answer to my own question. In case anyone was wondering the same thing....:
From NAFCU on Reg CC: "The presence of void language on the substitute check can be problematic to the extent that the recipient of the substitute check is unable to determine if the substitute check reproduced a fraudulent original item that contained clear void language before it was truncated or a legitimate original check on which the void language was latent. A person that suffered a loss because of this uncertainty would have an indemnity claim under 229.54 and possibly a recredit claim under 229.54."
