I wouldn't read too much into this. Lee Hyun Il is not back from retirement any more than Kim Ji Hyun, Huang Sui, or Hwang Ji Man were. In the case of Lee or Kim Min Jung playing in Jeonju this week, you have the fact that the event is domestic and they don't need any special permission to represent Korea overseas. Also, the dozens of non-national team players are playing with their domestic team logos and with their domestic team coaches and have been encouraged to do so by the Association. Korea has only had one tournament in the last 7 years that had players of various age groups in the same draw so they seem to be letting this event fulfill that niche as well.
