Outlook 2011 Junk Protection Exchange 2013 Questions

I seen how Microsoft disabled the Junk Protection Options menus when Outlook 2011 is connecting to an Exchange 2013 account.  However, I noticed that when a message is in the inbox, you still have the option to "block sender" or "mark as junk".  On the flip side, if a message is in the Junk folder, you have the option to "mark as not junk" or "allow sender".  In the case of Outlook 2011 connecting to an Exchange 2013 account, what function do those options serve if the junk filtering is actually handled by the Exchange server?
