Because DCC and non-DCC sales are all considered sales in Chase's system.

I see some PRC banks are promoting dual currency cards with 10X points for foreign spending on Visa/MC channel. I did use one in USA about 8 years ago, but once we canceled the purchase after swiping but before signing, then this authorization stayed on the 建行 Visa/UP card for months!

That's when I realized it's better to use a local CC, because 建行rep didn't have any clue what should be done, and kept telling us to go to the merchant for help...
