Probably because your cursor would become invisible if the window is
scrolled 40 columns to the right.  Emacs doesn't let you scroll the
window so that the location of the cursor becomes invisible.

Try "C-x 3", then "C-u 50 C-f", and _then_ evaluate the above
expression.  I think you'll see then that it works.
