Generic email templates for Notifications in Expenses Workflow

We are upgrading from image 11 to 31: 

1) We noticed that when a submitter/employee (not the delegate) submits an expense report, the email notification is sent to the approver/supervisor
in the To list. But the submitter/employee also is cced in the email sent to the approver. We use the Oracle delivered Generic Template name - "Expense Report Routing"
Can you please let us know if this was a recent change in adding the submitter in the CC list whenever an email is notified to the approver for his approval?

2) Employee/submitter email address is mentioned twice (TO as well as in CC) in incase of denial of the report when the delegate keys in the report for the submitter/employee.
