Anyone else notice that her hair is just about bun length when she runs up to and away from the drink stand, but when she breaks the railing away, her hair is knee length?

This is, I believe, the second major run of this commercial in the US. I saw the clip or pix on another site ( European I think, before I ever saw it on TV here in the States. I think we saw the knot tying, brunett her before the blonde.

I'm sure someone will correct me if I'm wrong...
