Should local Documentation match reference.wolfram.com?

Question

I've searched here for similar questions but was unable to find any. I have a specific example where my local documentation does not match the documentation on http://reference.wolfram.com/language/ (in this case, Databin). I've tried using a few, but not all, of the additional forms for Databin online. The forms I've tried worked, so my mma functionality seems to match the online documentation. There may be other cases. I'm just curious if this is normal? If not, is there a way to get them synchronized? I'm using mma v10.0.2. I have AllowDocumentationUpdates set to True in my global preferences.

Here's a sceen grab of my local documentation:

After contacting WRI support, I received the following response:

The local documentation updates with Wolfram Mathematica. The most updated documentation would be the version on http://reference.wolfram.com/language/. The documentation update option may be irrelevant and has already been reported.

So, local documentation only updates when Mathematica is updated. The option setting is apparently unused.
