When an absentee ballot which has been voted shall be returned to the board of registrars, it shall be deemed to have been voted then and there; and no other absentee ballot shall be issued to the same elector. However, if an elector who has requested to vote by absentee ballot based upon the reason that the elector is required to be absent from the elector's precinct during the time of the primary or election in which the elector desires to vote is present in the precinct of the elector's residence during the time the polls are open in any primary, election, or runoff for which the elector has requested an absentee ballot or if the elector's circumstances change and the elector is no longer eligible to vote by absentee ballot under Code Section 21-2-380, such elector shall have the absentee ballot canceled in one of the following ways:

(1) By surrendering the absentee ballot to the poll manager of the precinct in which the elector's name appears on the electors list and then being permitted to vote the regular ballot. The poll manager shall mark "Canceled" and the date and time across the face of the absentee ballot and shall initial same. The poll manager shall also make appropriate notations beside the name of the elector on the electors list. All such canceled absentee ballots shall be returned with other ballots to the superintendent;

(2) By appearing in person before the registrars or the absentee ballot clerk and requesting in writing that the envelope containing the elector's absentee ballot be marked "Canceled." After having satisfied themselves as to the identity of such elector, the registrars or the absentee ballot clerk shall grant the request and shall notify the managers of the elector's precinct as to such action so as to permit the elector to vote in person in that precinct. If the absentee ballot is in the possession of the registrars or the absentee ballot clerk, it shall be promptly marked "Canceled" and the date and time written across the face of the envelope. If the absentee ballot is in the mail or its exact location is unknown, the registrar or the absentee ballot clerk shall write "Canceled" beside the elector's name on the master list of absentee voters and shall cancel the ballot itself as soon as it is received. Canceled absentee ballots shall be disposed of in the same manner as provided in subsection (a) of Code Section 21-2-386 for absentee ballots returned too late to be cast.
