Of course there is no formal definition of a backing bean but this would be my take:
Backing bean is a managed bean that backs the view. Another term for the backing bean could be "view bean".

It looks to me like they use it in the sense of "an object that can be referenced from an EL expression" - which will usually be a "managed bean", though it could be any object that has somehow been placed into the request/session scope. I guess they can't use the term "managed bean" in this case, because the referenced object doesn't *have* to be something created via a <managed-bean> tag, though it usually will be. I'm not sure the term "backing bean" is really appropriate though. Still, the meaning is pretty clear in context - though the original poster is right that it is a little bit slack for a spec to use terms that have not been defined.
