No, I understand what he says. After the drag-scroll your cursor is in the center, but because you drag scroll your physical mouse is not in the center on the pad and you need to move it back to the center of the pad to match the position on the screen. He wants that the cursor after the drag scroll went to position where it would be, if he just moved the mouse.
I personally think that this would not be added, because it is not that simple to code into the game.
Because of exactly that reason, I use inverted drag scroll (there is an option for that), so I place the mouse in the corner and move it to the center, so it works perfectly.
