Such person shall be reenrolled in the retirement system and shall contribute thereto at a rate based on his age at the time of reenrollment. Such person shall be treated as an active member for determining disability or death benefits while in service and no benefits pursuant to an optional selection with respect to his former membership shall be paid if his death shall occur during the period of such reenrollment.
Upon subsequent retirement of such member, his former retirement allowance shall be reinstated together with any optional selection, based on his former membership. In addition, he shall receive an additional retirement allowance based on his subsequent service as a member computed in accordance with applicable provisions of this article; provided, however, that his total retirement allowance upon such subsequent retirement shall not be a greater proportion of his final compensation than the proportion to which he would have been entitled had he remained in service during the period of his prior retirement. Any death benefit to which such member shall be eligible shall be based on his latest retirement, but shall not be less than the death benefit that was applicable to his former retirement.
