     (5) A security interest described in subsection (4) becomes unperfected as against a purchaser of the goods for value and is deemed never to have been perfected as against a purchaser of the goods for value if the applicable requirements for perfection under 30-9A-311(2) or 30-9A-313 are not satisfied before the earlier of:
     (a) the time the security interest would have become unperfected under the law of the other jurisdiction had the goods not become covered by a certificate of title from this state; or
