I think, I know what he means.

Current behaviour:
You are at the top of an list with an pulley menu. If you drag your finger down the display, the menu opens (item by item). When you movement overshoots the display, the menu gets fully opened, so that you can tap on a menu item.

His suggestion:
When you are in the middle of a long list, you should be able to open the pulley menu with the same gesture. You move your finger down (which at first scrolls the list a bit up) and as soon as you overshoot the display, the list scrolls to the top and the pulley menu is fully opened.

I hope, I understood it correctly
