Where two (2) or more beneficiaries are designated to take successively or alternately by reason of survivorship under another person’s disposition of property and there is no sufficient evidence that these beneficiaries have died otherwise than simultaneously the property thus disposed of shall be divided into as many equal portions as there are successive or alternate beneficiaries and the portion allocated to each beneficiary shall be distributed as if he had survived all the other beneficiaries.
