Well I suggest you try it go to the end of a line and run 
M-x forward-word you'll be on the next line after the first word.
In this case
is current-line > line -> I go back one line with (goto-line) and
there I move to the end of the line if I' do not move down line
nothing will happens. So what is it if you move move forward a word
and move down a line you go back and than to the end of the current
line. That makes no sénse.

For what?
