No, I'm saying even in that case you know it was intended to be a copy. If you wanted that to be a reference then you'd either (a) just do the obvious thing which is to just use the original variable name instead of creating a new variable out of the blue for no reason, (b) leave a comment explaining why you're not doing the aforementioned obvious thing, or (c) use a self-explanatory variable name to provide the explanation instead of a comment.
