Xinput is probably referring to windows Xinput, not Linux. (Linux xinput is not the same and not in use by cemu) Cemu primarily supports SDL on linux.

For SDL, instead of manually switching the values of the Switch Pro Controller, the SDL hint SDL_HINT_GAMECONTROLLER_USE_BUTTON_LABELS could be used. (It's enabled by default)
