skeet surfer, the way I read it the first sentence of your quote sums up all you need to know.
'A pass in the ATPL theory examinations will be accepted for the issue of a CPL or IR during the 36 months from the end of the month of the date of the final pass in the examinations.'
All the rest is with reference to the validity of the exams for an ATPL issue. Unless you do both the CPL and IR in the 0.5 years you will need to resit exams.
