A judge is going to need to sort this one out. It is certainly possible that the actions of the mother-in-law would serve to "revive" the earlier Will. This is not something that would automatically happen. There would also be a chance for someone to argue that your mother-in-law lacked capacity, at the time the second Will was revoked and that her revocation should either not be effective, or that the estate should be handled under intestacy. The court is tasked with the job of determining your mother-in-law's intent and whether or not she had capacity, as well as determining whether the actions were the result of undue influence. Your case is a perfect illustration of why it is so important to handle all estate planning matters through a qualified attorney.
