Mirror state in Sprite Animation

In Unity 4.3 is the mirror checkbox in a state mecanim suppose to work with SpriteRenderer like flipping the texture without having to negate the x scale of the object?
I have checked it and nothing happened.

Thanks.

The Unity 4.3 - 2D Game Walkthrough at about 8:15 sets the local x scale to -1 to handle their flips. My own experiments confirm that the sprite is not flipped when mirror is checked, but 3d models work. I don’t think it’s a bug, it’s either intentional or an oversight.

I’ve posted a feature request for this, maybe we can get it implemented in a future version:
