You're talking about the configuration-selection code, not the driver-matching code. usb_choose_configuration() selects the first config it considers acceptable, regardless of what drivers are available. Both BOT and UAS would be acceptable, so it comes down to which descriptor occurs before the other. If you want to use a different config, you have to switch the device yourself, for example by writing to /sys/bus/usb/devices/.../bConfigurationValue.
