Yes, thanks for the addition, for me they seemed trivial, but first-time ICN:ers might get caught by it.
Going landside is not a biggie though, but frustrating - train from the concourse to the terminal, go through immigration, go to departure, pass immigration and security again and back to the concourse. If the turnaround is ca. 2 hrs, it's still manageable, but a PITA.
