After the voter has marked his absentee ballot, he shall (a) enclose the ballot in the envelope provided for that purpose, (b) seal the envelope, (c) fill in and sign the statement printed on the back of the envelope, (d) enclose the ballot envelope and any required assistance form within the envelope directed to the general registrar, and (e) seal that envelope. A voter's failure to provide in the statement on the back of the envelope his full middle name or his middle initial shall not be a material omission, rendering his ballot void, unless the voter failed to provide in the statement on the back of the envelope his full first and last name. A voter's failure to provide the date, or any part of the date, including the year, on which he signed the statement printed on the back of the envelope shall not be considered a material omission and shall not render his ballot void.
