This brings us back to an old thread on this subject and this graphic from mike holt that I modified. The connecting edge, IMO is 2' off the wall and the 2" section would be part of the wall base cabinets even if constructed as one pieceThat is not how it is normally interpreted. The problem is they don't give us anything except connecting edge. Why even mention connecting edge if it is the wall. It would be unnecessary
Now put a sink in there and we are back to our original question. I think we all agree one is needed there but do we install one?
