Because Lenovo does not put any port at the back side of the computer (they are all side ways), so using the hardware dock will expand the existing infrastructure. And you are able to charge the ThinkPad while the ThinkPad is docked.
This does not happen in USB dock. At least, you need 2 charger to make everything work. And you will have one less USB port available.
Completely untrue. My ThinkPad X1 Carbon runs with a ThinkPad USB-C dock. One connector, through the USB-C/power port. It charges while connected. My USB keyboard, mouse, headset, monitor, and other peripherals are all picked up fine. Plenty of ports left. There's an extra USB and powered USB-C port on the front.
