Start and due dates are independent concepts. Start date is just the date before which you do not wish to be shown this action (or project) as available for action, because you either do not wish to work on it or are not able to work on it. Ideally, the start date will be prior to the due date, but as far as marking something due soon (or overdue), the start date doesn't matter; it gets the due soon (or overdue) styling based on the due date. It's worth noting that this is done based on the actual time of the due date; if you have your "due soon" window set to 2 days, something becomes due soon exactly 48 hours prior to its due date. Something due Wednesday at 11pm is marked due soon Monday at 11pm, even though some might regard Wednesday evening as in the next 2 days on Monday morning...
