The difference is the "additional classes" and the break tag at the end. Sometimes its needed, and sometimes its not. Yoou can tell you need one if you have a "blank" spot at the bottom of your rounded box.
You can use the same code for your customer/dialog.tpl and customer/menu_dialog.tpl.
Just remember, it will screw up your checkout page, the one were it asks if you are a returning customer or a new one. What I did was use the original customer/dialog.tpl (renamed to flc-dialog.tpl) and called it in skin1/modules/Fast_Lane_Checkout/checkout_0_enter.tpl.
You can also change the colors between the two (menu and main page dialog) by adding the classes xboxcontent2 (for the main background) and color_b (use it at the bottom instead of color_a), making them whatever color you choose (everything else is the same).
