The highest offense of which a person may be convicted in such an instance as set forth in subsection (1) of this section shall be determined by hypothetically assuming each statement to be false. If perjury of different degrees would be established by the making of the two statements, the person may only be convicted of the lesser degree. If perjury or false swearing would be established by the making of the two statements, the person may only be convicted of false swearing. For purposes of this section, no corroboration shall be required of either inconsistent statement.
