Nope. To repeat, it's a "deliberate interruption of a journey at an intermediate point from which the passenger is scheduled to depart later than 24 hours after arrival".

If there are no outgoing flights within the 24 hour timeframe, then it is not a deliberate interruption and therefore it is not a stopover; however, GDSs don't price this automatically (I believe because when they were programmed it would have been too resource-intensive to perform a schedule check), they simply assume that >24 hours is a stopover, so whomever issues the ticket needs to manually override the stopover in the fare calculation/ticketing command. This rarely happens in the developed world, but can happen in remote areas (I've seen it in the Southern Pacific Islands).
