(a)the reference in section 19(1)(b) of that Act to the number of penalty points shown in respect of an offence in Schedule 7 to that Act or to a number falling within a range of numbers so shown shall be read in relation to the offence mentioned in subsection (1) above as referring to the number so shown in respect of that offence or (as the case may be) to a number within the range so shown, reduced in either case in accordance with subsection (2) above ; and
(b)the reference in section 19(3)(a) to any penalty points that on the occasion of a person's conviction will be ordered to be endorsed on any licence held by him or would be so ordered if he were not then ordered to be disqualified shall be read as referring to any such points that will or would be so ordered after reduction in accordance with subsection (2) above of the appropriate number of penalty points for any offence of which he is then convicted.
