Singapore Airlines KrisFlyer - Bank of China SQ Visa

I don't understand the 25,000 gifts points for additional card.

Perhaps this should go into the KF CC thread?

I understand it's
- principal spends HK$2,000 for 2,000 KF miles
- application of each additional card gives the account 25,000 miles. 10 pts per KF mile.
