inject mocks: wrong example?

https://github.com/WebJournal/journaldev/blob/master/Mockito-Examples/src/test/java/com/journaldev/mockito/injectmocks/MockitoInjectMocksExamples.java

when/thenReturn should be done against
emailService and smsService and not against
AppServices(|1|2) instances

or the author doesn't understand idea of mock injection
