how to process the ss differencial signal

I am trying to design a new board with CYUSB3014-BZXI and with type A usb3 interface.
From SuperSpeed Explorer Kit Schematic.dsn I notice the STDB_SSRX- Pin of TypeB USB3 interface is connected to net SS_RX_P and the STDB_SSRX+ Pin of TypeB USB3 interface is connected to net SS_RX_M, which is mismatched. then I realized this design that exchanges signal between differencial pair make the PCB layout efficient and improve the signal integrity.
My question is whether the SS_TX_P/M could be exchanged likewise, whether the D+/- could be exchanged likewise?

thank you very much!

Hi fengjiefu,

   

 

   

The SSTX_P/M could also be swapped. But the D+/-  could NOT be swapped.
