I'm not sure if you noticed, but she was doing the interview via webcam from New Jersey. Also, it seems that her participation was facilitated by the Korean NGO GOAL:

This is a little off-topic, but there's actually a long history of using TV and radio to reunite separated family members in Korea. During the division and war, and confusion afterwards a lot of families got separated. Many didn't know if spouses, parents, siblings, etc were even alive, and if they were where they could be, so in the 70s and 80s the Korean branch of the Red Cross partnered with various South Korean media to give such people air time to say what family members they were missing and descriptions of where they last saw them. It was really popular and helped a lot of people find their missing families. Unfortunately there are still a lot of cases where accident or geography or politics has prevented separated families from being reunited.
