Absolutely correct. Your 5DSR has a mini USB 3.0 female connector, and you can see the male counterpart on the right of the photo. The large plastic piece has 2 screw connectors that screw into the camera body.
If you never tether your camera to your pc, then your cord is just another 3.0 usb standard to mini cable with a superfluous connector.
It screws into the camera body? Interesting, I've never seen that. Nikons don't have them.
