In the event a member who is receiving a retirement allowance due to a disability secures gainful employment, including employment with the city, paying more than the difference between his retirement allowance and his average final compensation, the amount of his retirement allowance shall be reduced to an amount which, together with the amount earnable by him, shall equal the amount of his average final compensation but, in no event, to an amount less than the portion of his allowance provided by his accumulated contributions. Should his earning capacity be later changed, the amount of his retirement allowance may be further modified in like manner.
