It is the total number of passengers transferring between Aer Lingus and Malaysia Airlines. It wouldn't make sense to count only those bound for KUL, or conversely to only count those bound for destinations beyond KUL (and I fully expect this latter group to be much larger than the former, and that Australia would represent the single biggest destination).
My last trip with MAS - in 2014 as it happens - was on an EI/MH ticket from Dublin to Sydney. My first ever trip to Australia in 2002 was on a bmi/Malaysia ticket from Dublin to Sydney - but EI provided all the Irish feed for MH after their departure from DUB.
