You’re correct about the specs of the device. However, after announcement/release there was controversy that the cable included in the box is only capable of USB 2.0 transfer speeds. But Marques Brownlee pointed out that the same is usually true with the included cable for Android devices too. I got a portable SSD to use with my iPad Pro and it just comes with a short high-speed cable anyway…
Edit: The included cable with the iPad is also only 2.0 speeds, even though it has a USB4 40Gbps port.
