That seems awfully expensive for 12 hours at a 3-star hotel even considering the convenience factor. Must be for one day, I think. You can't expect the booking sites to have contingencies for every variation of the hotels.
You can contact them directly: The FAQ and rates pages explain exactly how it works. Note that there are 10% + 10% additional charges on top of the Korean won prices.
I use 'Skype out' so the phone call would cost almost nothing, but there's an e-mail on the contact information page as well.

As a transit hotel, it allows those with international connections to sleep and refresh before an onward journey. If you will click through to the Arriving/Leaving link, it explains:
This hotel is located in the customs area of the airport, and only international travelers can access the property. Guests are asked to communicate in advance the number of their flight, and their check-in and check-out times at the time of booking. Contact information is provided in the reservation confirmation email. The hotel is located in the customs area, so guests should not pass immigration. Luggage will be transferred to the guest's next flight. To reach the hotel, guests must follow the transit arrows to boarding gate No.43/No.11 on the 3rd floor, then take the escalator near the gate to the 4th floor.
