That's what most people are talking about, yes.
Some others will define it a bit differently, stating that the right hand path is about doing no harm, and the left-hand path has no such compunctions, but this doesn't always mean that someone using left-hand path work is evil. (Killing a virus, for example, is doing harm).
My opinion is it's a rude term put forth by the self-righteous. Rude, because the term's based on an old superstitious misconception that left-handed people were evil. They used to try to force left-handed kids to learn to write with their right hands.
Folks who have certain religious beliefs about karma or the threefold law or whatever like to state that it's immuteable law that if you do something that harms another thing, you're going to get it in the teeth many times over, so anyone who does that sort of thing must naturally be insane and self-destructive.
Personally, I've seen nothing to indicate any of this.
I consider myself none of the above--I do what I feel is necessary for the situation.
