In any prosecution under this section, the falsity of a declaration set forth in the indictment or information shall be established sufficient for conviction by proof that the defendant while under oath made irreconcilably contradictory declarations material to the point in question in any proceeding before or ancillary to any court or grand jury. It shall be a defense to an indictment or information made pursuant to the first sentence of this subsection that the defendant at the time he made each declaration believed the declaration was true.
