That's what I thought too, but you actually don't have to do the face ID when it's next to NFC reader. You double click the side button, while looking at the phone - it lets you choose which card you want to use for the payment, ONLY THEN you tap the phone to the NFC range, you don't need to look at the phone anymore after you unlocked it with a double click.

Yeah you don't need to do them at once, but with Touch ID you could authenticate in one smooth motion to the NFC machine rather than having to go up to your face first.
