BranchCache client cache encryption

Question

On one hand, TechNet says this about BranchCache in 2012 and 8:
What’s new in BranchCache in Windows Server 2012 and Windows 8
Cache Encryption. Cached data is now stored encrypted by default.  This allows you to ensure data security without using drive encryption technologies.
http://technet.microsoft.com/en-us/library/jj127252.aspx
Then in BranchCache Overview it says this:
Data that is stored in the content cache is not encrypted, so if data leakage is a concern, you can use encryption technologies such as BitLocker or the Encrypting File System (EFS).
A paragraph later it says this:
Hosted cache servers that are running Windows Server 2012 encrypt all data in the cache by default, so the use of additional encryption technologies is not required.
http://technet.microsoft.com/library/hh831696(Other posts here in the forum asking similar questions are generally referred to this article)
It seems clear that the cache is encrypted by default on the server.  But what about the client?  These articles appear to be in contradiction. Either the client cache is encrypted in Windows 8 by default or it is not.  So which
is it? 
THANKS!
(If it's only server cache, then an update is needed in the What's New in Windows Server 2012 and Windows 8 section because no distinctions between client and server is made there.  This is misleading)

Hi,
Thanks for your post.
According to the MS article, Hosted cache servers that are running Windows Server 2012 encrypt all data in
the cache by default, so the use of additional encryption technologies is not required.
BranchCache is designed to prevent unauthorized access to content. Content is encrypted when transferred between peers or between clients and the hosted cache server. Content can only be decrypted using the identifiers provided by the content server in the
main office.
