That's a prefetch.  Each instruction fetches the *next* instruction, 
ahead of time.  Pre=next.  I don't know why you are confused.

If you try to communicate, call things the way they are.  If it looks 
like a duck, quacks like a duck, swims like a duck, walks like a duck, 
flies like a duck, it is called "duck".  If you fetch the next 
instruction while you are still busy with the current instruction, it is 
a prefetch.

The diagram of a two-stage pipeline is

fetch | execute |
        fetch   | execute |

You do the fetch *before* you are *done* with execute (my words).  So 
*concurrent* with execute (your words).  Can you transform these two 
identical statements into each other so we can agree that we agree?

Yes.  That's why prefetch is a low-hanging fruit, and done most of the 
time.  As your example shows.

Well it is, according to your description of what happens.  See above.  
You fetch the instruction in one cycle and execute it in the next cycle.  
"one" + "next" = 2.

The confusion might be that you think of an instruction as doing two 
things:

a) execute itself
b) fetch the next instruction

These two mostly independent operations happen in parallel.  The 
conceptual entity however is *one* instruction, not two of them.  One 
instruction is executed by

a) fetching it
b) executing it

This is a sequential process, taking two cycles.

Your mental model as above makes it easier for you to deal with the 
paralleism, and make sure there are no pipeline stalls in any case.  No 
argument about that.  This is just a discussion about terms.

It moves the entire fetch operation by one cycle - start of decode is 
end of fetch.

Of course "syntactic sugar" has a defined meaning.  It is a syntactic 
element that makes the program easier to read, while having no function 
of its own:

http://en.wikipedia.org/wiki/Syntactic_sugar

I.e. to get HP's syntax, you define

: endif  postpone then ; immediate
: then   postpone if ; immediate
: if     ; immediate

and then you can write something like

: simple. ( n -- ) if dup 3 > then drop ." many " else . endif ;
\ numbers are 1 2 3 many...

IF in this case is obvious syntactic sugar, as you can leave it away 
without changing the functionality of the program.
