That's correct. It looks like Cal was forced into a new home and home because UNC asked to take a two year break after this year, so Cal was left scrambling to fill the void. UCLA is only on their schedule for two years.
UK and UNC are playing in the same tournament for the next two years, and they didn't want to have to play twice in the same season. As soon as their involvement in the tournament is over, UK and UNC will resume as always. UNC has already sent UK the contract to renew the series following the two year break. http://www.courier-journal.com/story/sports/college/kentucky/uk-beat/2014/11/28/calipari-uk-unc-home-and-home-returns-in-2017/19618493/
