How @Transactional timeout works with multiple dataSource

Question

So here is the example, I have method where I defined timeout=10 seconds for DS1. now this method is also calling another transactional method for DS2. Will time taken by DS2 response also considered here for timeout?

MainService.java

@Transactional(value = "transactionManagerDS1", timeout = 10)
public void tranTest(){
    try {
        DS1service.sleepDS1(1);
        DS2service.sleepDS2(10);
        DS1service.sleepDS1(1);
    }catch (RuntimeException e){
        logger.error(e.getMessage());
    }
} 

Now these DS1service and DS2service do select sleep for respective seconds

@Transactional(value = "transactionManagerDS1")
public void sleepDS1(int sec) {
    SQLQuery query = getCurrentSession().createSQLQuery("select pg_sleep(" + sec + ")");
    System.out.println(query.uniqueResult());
}

@Transactional(value = "transactionManagerDS2")
public void sleepDS2(int sec) {
    SQLQuery query = getCurrentSession().createSQLQuery("select pg_sleep(" + sec + ")");
    System.out.println(query.uniqueResult());
}

here time taken by DS2 query also counted and timeoutException were thrown.Is it correct behaviour?
