The pins on the upper and lower side of the connector are rotational identically. They only different on rx or tx. Then there’s a pin that detects the orientation and the controller handles switching the rx/tx if need be.

Traditional connectors need rx on one side to connect to tx on the other side. Now if rx connects to rx, the controller switches its rx to tx.
