I don't see your basis for that claim from skimming the article. The 
only thing that looks like the Dock is a toolbar at the bottom of 
this image:

I think that you can see it's a toolbar if you compare it to the 
OpenStep image here:

If you can point out a reference to a Dock-like representation of 
running tasks in that article, please quote it. I simply may be 
missing it in my quick skimming through the article.

In any event, Bruce Tognazzini, one of the "fathers" of the Mac UI, 
thought that many aspects of the Dock (and the basic concept, though 
I can't find his review of the original release of OS X where he made 
this explicit) was copied by Apple from the Windows TaskBar. Here's a 
quote that makes it explicit, in his article "Top 10 Reasons the 
Apple Dock Still Sucks":

     4. The Dock's locations are unpredictable  

     Apple's solution to the early fire storm of protest over the Dock
     was to allow the user to hide it. That way, it doesn't float over
     all your applications. Slide below the screen with your mouse and
     the Dock appears. 

     This Windows copy job, unfortunately, suffers from the same defect
     as the Windows Task Bar: You can't predict where a given object is
     until you reach the bottom of the screen and cause the Dock to
     appear. Worse than with Windows, your job is not over. Now, you
     begin the task of scrubbing the length of the Dock, trying to force
     the labels to appear, hoping you won't go far enough out of range
     in the process to cause the bar to disappear on you. (The Dock is
     linear; the human hand was designed to move in an arc. We don't do
     well with scrubbing.) 

Now right here, he's referring to the autohide as being copied from 
Windows, but elsewhere (in articles I can't find), he made extensive 
comparisons of the Dock to the Windows Taskbar, treating it as an 
effort by Apple to copy from Microsoft, and showing various things 
that Apple had gotten wrong in the copying, as well as things that 
were wrong with Microsoft's implementation that Apple didn't correct.

Ah, yes, found it, in his first look at OS X:

http://asktog.com/columns/034OSX-FirstLook.html

Under the heading for "The Dock" he writes:

     . . . The deleterious effect of this emphasis can best be seen in
     the Dock, a graphical equivalent to Microsoft’s Task Bar. 

That's not exactly the statement of "copying" that I was remembering. 
In reviewing the rest of the article, it seems to me that this is not 
the only article I'm recalling, but maybe I'm misremembering.

The point is that nowhere does Tog see the Dock as being an 
adaptation from NextStep, so I'm rather skeptical of the claim of 
derivation of the Dock from Next.
