A reversal's part for each party is its original's negated, never read
from the reversal's own lines. A member paying the company's card from
their own funds (Dr card / Cr due to members), tagged with the card's
issuer, is paid to the issuer; its reversal takes that back, so the pair
nets to zero; reversing the reversal pays it again.
