Difference between the two USB ID pins?

Hello,

 

I'm planning to use 8M Mini's USB ports in OTG mode. I saw that both USB ports have 2 ID pins. For USB1, it is signal usb_id, located on pad USB1_ID [D22] and usb_otg_id, located on pad GPIO_IO10 [AD10]. Are these ID pins redundant? Or do they accomplish different things? Just trying to figure out if I need route one or both to the USB connector.

 

Thanks
