Is Leblanc's "Shadow of the Rose" Supposed to do damage?

Ok, this is a quick one. I know her abilities don't do damage (The clone) but what I've noticed is her autos, (and the mimic ones) do a bit of dmg I have ulted a clone at someone with very low HP to maybe try to pop flash, but twice now the person was in shop I suppose so they just sit, and my clone ran out of time or something, it never cast the ability, it just sat there and autod them to death :o

I think it's cool, but maybe a little unfair to play against? not sure, but was it intentional?
