That's also how I'd understand this. Just had another look at the docs, where it defines the input power support on page 15 with:

• Power adapter with fixed voltage from 5 V to 20 V on the USB C power port
• Support USB Type C PD 2.0, 9 V/2 A, 12 V/2 A, 15 V/2 A, 20 V/2 A

So (but it's still guessed), it is fixed to the 5V for the fan.
