Joint Tenancies: Notice and Periodic Tenancy

The Superstrike Ltd v Rodrigues 2013 court case, which revolves around the concept of a Statutory Periodic tenancy (a type of tenancy that continues after the fixed term ends), determined that such a tenancy is a new tenancy. Therefore, is there a valid argument that if one joint tenant gives valid notice to vacate a property on the last day of the fixed-term tenancy, any remaining joint tenants solely enter into a brand new tenancy the day after the fixed term ends, and the vacating tenant is no longer liable for rent, etc.
