Hibernate 语句执行顺序问题

代码：
private static void editInfo() {
    Session session = null;
    try {
        session = HibernateUtil.getSession();
        if (session != null) {
            session.beginTransaction();
            Person p = new Person("王三", 22, "男", "北京");
            session.save(p);
            session.delete(p);
            p.setId(null);
            session.save(p);
            session.getTransaction().commit();
        }
    } catch (Exception ex) {
        if (session != null) {
            session.getTransaction().rollback();
        }
        ex.printStackTrace();
    } finally {
        HibernateUtil.CloseSession();
    }
}
控制台显示：
Hibernate: 
insert 
into
    PERSON
    (NAME, AGE, GENDER, ADDRESS) 
values
    (?, ?, ?, ?)
Hibernate: 
delete 
from
PERSON 
where
ID=?
Hibernate: 
insert 
into
PERSON
(NAME, AGE, GENDER, ADDRESS) 
values
(?, ?, ?, ?)
