RealmList move - unexpected results

Group

public class Group extends RealmObject
{
    private RealmList<Person> persons;

    public RealmList<Person> getPersons()
    {
        return persons;
    }

    public void setPersons(RealmList<Person> persons)
    {
        this.persons = persons;
    }
}

Person

public class Person extends RealmObject
{
    @PrimaryKey
    private int id;

    private String name;

    public int getId()
    {
        return id;
    }

    public void setId(int id)
    {
        this.id = id;
    }

    public String getName()
    {
        return name;
    }

    public void setName(String name)
    {
        this.name = name;
    }
}

Testing code

Realm realm = Realm.getInstance(this);
realm.beginTransaction();
Group group;
if(realm.allObjects(Group.class).size() == 0)
{
    group = realm.createObject(Group.class);
}else
{
    group = realm.allObjects(Group.class).first();
}
realm.commitTransaction();

for(int i = 1; i <= 10; i++)
{
    Person person = new Person();
    person.setId(i);
    person.setName("Name " + i);

    realm.beginTransaction();
    Person databasePerson = realm.copyToRealmOrUpdate(person);
    realm.commitTransaction();

    group.getPersons().add(databasePerson);
}

for(int i = 0; i < 10; i++)
{
    System.out.println("first list: " + group.getPersons().get(i).getName());
}

group.getPersons().move(1, 0);

// Gets handled correctly
for(int i = 0; i < 10; i++)
{
    System.out.println("second list - move up: " + group.getPersons().get(i).getName());
}

group.getPersons().move(0, 1);

// Same as second list, but should be the same as the first list
for(int i = 0; i < 10; i++)
{
    System.out.println("third list - move down: " + group.getPersons().get(i).getName());
}
