I don't understand what this is trying to say. All properties have either their own settings associated or else use the "global" settings, no? The only way I see for properties to be unaffected is if they have no associated QSettings (i.e. they don't have their own *AND* the "global" settings instance is unset). As it is currently written, this statement seems to be incorrect.
