I'm not sure what you mean by this.

I've not looked very carefully at the Leopard screen-shots yet, so I'll refrain from commenting in that direction. All I'm saying is both my wife and myself found the redesigned UI on the apple.com website, specifically the nav bar across the top, to look rather similar to vista.

I hope that clarifies; please don't loose sleep over this observation if it doesn't jump out at you.
