Since you only copied the least important part of the quote, let me emphasize it:
(b) Provided that an IR(A) is obtained in
accordance with (a) above, a pass in the
ATPL(A) theoretical knowledge examination will
remain valid for a period of 7 years from the last
validity date of the IR(A) entered in the CPL(A)
for the issuance of an ATPL(A).
