It would genuinely surprise me if that is what the feature is for. Not only does SK typically not have the technical skill set for such an advanced feature but it is also not something that works in the interest of the airline(s). If you're checked in separately for your connecting flight, the reason for your delay or not showing up is completely irrelevant to the connecting flight staff. Either you are there or you are not. Different story if it was one itinerary.

Nevertheless I'm interested to find out what it is intended for.
