I worked with usbc

The answer is that literally you have double the connections you need for certain things. The connection uses differential signals which don’t care about the orientation.

Usbc does know the orientation of the connection. An example is analog audio over usbc (supported by some Android phones).

I personally worked on hardware and software that determined the orientation of the connector and configured switches to get the signals in the correct place.
