I think you are.  I was thinking about the truncate-lines==nil or word- 
wrap==t case.  Maybe I didn't

The next visual line would have to be pushed downward, but I don't see  
how it would affect the visual lines resulting from the current buffer  
line.
Also, the next visual line isn't visible anyways because it is beyond  
the last displayed line.  We're proposing to stop processing a buffer  
line when we have left the portion of the buffer that is currently  
visible in the window.

(The truncate-lines==t case is something else of course.)
