Spring Data JPA save list entity return list in same the order?

Does the method in Spring-Data-JPA's CrudRepository 

 <S extends T> Iterable<S> saveAll(Iterable<S> entities)

return list in the same order ?

In that version an actual List is the return type: 

@Transactional
public <S extends T> List<S> save(Iterable<S> entities) {

    List<S> result = new ArrayList<S>();

    if (entities == null) {
        return result;
    }

    for (S entity : entities) {
        result.add(save(entity));
    }

    return result;
}

so if you pass a List to the method, you will get the result in the exact same order as the ArrayList is the implementation.
