I agree with "Abnormal", USB-C are inputs. It's probably a mistake.

Yes, aren't the two USB Type C the "inputs" of this USB hub?
Maybe I'm misunderstanding the definition of "outputs" and "inputs".
In my opinion, the "output" is the interface between the USB hub and the laptop.

This USB hub has two USB Type C outputs, but connects to external devices via a standard USB Type A.
