Head First Java -- a new, unreported errata

Head First Java Book 2nd Edition 2005
I have searched the errata for the book but did not find this

Page 620 (Chapter 18)

MyRemote service = (MyRemote) Naming...

Arrow pointing to MyRemote says:

"The client always uses the remote implementation as the type of service..."

In my opinion this should read:

"The client always uses the remote interface as the type of service..."

Change 'implementation' to 'interface'.

Do you agree. Is this an error in the book?
If not, please explain.
Thanks for your help.

Since one can't really use an interface for much of anything other than specifying an implementation, I'd side with the book.
