The date on which the retirement system mails, or electronically transfers in the event of an electronic funds transfer, payment of any portion of the accumulated contributions credited to a member's individual account in the employees saving fund pursuant to the Government Code, §842.108 is the date on which the person's membership in the retirement system terminates under §842.109 of that code as a result of that payment. However, if the payment by the retirement system was made by check or checks and all such checks are returned to and received by the retirement system within 30 days of such date, together with the person's written request to be reinstated as a member, the person's account shall be reopened to the same effect as if the payment to the member had not been made.
