'local_addr_used' y 'add_addr_accepted' se decrementan para direcciones no relacionadas con el subflujo inicial (ID0), porque las direcciones de origen y destino de los subflujos iniciales se conocen desde el principio: no cuentan como \"direcci\u00f3n local adicional en uso\" o \"ADD_ADDR aceptada\". Luego, se requiere no incrementarlas cuando el punto de entrada utilizado por el subflujo inicial se elimina y se vuelve a agregar durante una conexi\u00f3n. Sin esta modificaci\u00f3n, este punto de entrada no se puede eliminar y volver a agregar m\u00e1s de una vez."
