In more detail, the Language Reference describes how containment interacts with event broadcast and reception <http://docs.puppetlabs.com/puppet/4.3/reference/lang_relationships.html#refreshing-and-notification> (the mechanism underlying resource notification and refreshing).

One thing to watch out for, however, is that the event broadcasting produced by a declaration such as you presented may be more than you actually want. That is, there must not be any resources in Class['site::config'] from which you do not want to receive events, nor any in Class['site::service'] to which the events should not be directed.
