Thanks.

Personally, my gut feeling is that we shouldn't introduce this
complexity in the tutorial.  Users coming from other editors are used
to saying "save the file" (and the evidence is the File->Save menu
item present in many applications, including Emacs).  So "save file"
is natural, whereas "save buffer into the file it visits" is less so,
and for newbies any complication at this stage is an obstacle.  It is
no accident that buffers are described in the tutorial only after
files.  (This is yet another reason why introducing buffers before
they are described in the tutorial might be a step in the wrong
direction.)

Bottom line: I think in this case accuracy is less important than
providing an introduction to Emacs usage that is as free from
complexities as practically possible.
