Usb speed limitations

According to the specification of the Jetson Xavier Nx :

[J6] and [J7] are each a stack of two USB 3.1 Type A connectors. Each stack is limited to 1A total power delivery. All four are connected to the Jetson Xavier NX module via a USB 3.1 hub built into the carrier board

Does it mean that maximum bandwidth of the usb 3.1 is splitted among 4 usb connectors?
Or each of this connector can process data with maximum usb 3.1 bandwidth?
