One is by definition "harmed" if the second preference beats the first. 
That's what is meant by "harm."

The notion that if you don't want to cause this kind of harm, you can
simply choose not to vote lower preferences, apparently doesn't grasp
the concept that the point of LNHarm is that you wouldn't then have to
make such a choice. (I've brought up before the analogy of claiming 
you're getting stuff for free by choosing not to purchase it.)

Under standard Approval strategy, it is of course possible that you might
approve your top two candidates.
