In practice there is no difference using SERIAL_CONSOLE with -L parameter or USB_SERIAL_CONSOLE. I have introduced this new variabile only for emphasize that physically is different and works in a different way (with -L param). When make a new conf you could save a lot of time viewing in code that is possible to use getty with a suitable configuration for your usb console only adding -L. Otherwise, unless new var adding, I can use SERIAL_CONSOLE with -L putting a comment in my machine/config file explaining that. And in a second time we can see if is correct to introduce a new var for this scope.
