The fallback for older browsers is misrepresented here. The construct presented here, var(--variable, default), is for when a variable is undefined. The fallback for older browsers that do not support variables would be defining the same attribute without a call to var() before a more modern definition, so the cascade will take care of unknown value by respecting the prior definition.
