yes-ish, that's the right configuration for a bottom right software button.
however, the buttons are aligned in a horizontal bar, so anything below the
top edge of the softbutton area counts as software button. the left edge
(3068 in your case) defines where the left button area starts. Hence:
anything below 4326 that is left of 3068 is a left software button.
