2294322 - Changing a Dependents Name also updates the Personal Info record of the Employee (who is also the Dependent)

John Smith is the Son of Miranda Smith and they are employed in the same Company.

When John changes his First Name in Personal Information > Personal Information portlet in Employee Central, his name also gets updated in Miranda's (his mothers)  Dependents > Personal Information section.

This same can be observed the opposite way around. Miranda updates her Dependents Information, and changes John's First Name to Johnathan. Then it is found that John's Personal Information record is updated

Is this an expected behavior?
