SSRXN connect to "USB_SSRXP_DN3"? SSRXP connect to "USB_SSRXN_DN3"??

J2 USB3_TYPEA_CONNECTER, is "SSTXN" connect to "IND_DS_TXP2" and "SSTXP" connect to "ND_DS_TXN2"?

J1 USB3_TYPEA_CONNECTER, is "SSTXN" connect to "IND_DS_TXP1" and "SSTXP" connect to "ND_DS_TXN1"?

Hello,
That is for ease of routing, both the PCIe and USB3.0 specifications allow for polarity swap.

Hello,

Yes, you can swap the polarity of the REFCLK and the SuperSpeed lines.
The schematic looks correct.
