I see.
I think in HKG, there are also some other rules whereby Cathay still needs to check the physical documents. One example I recall is if the ex-HKG boarding pass is printed by another airline at another airport (or something like that), Cathay will check the documentation themselves in HKG. Something like that. Perhaps that could be the case? Maybe a connecting flight?
