Science fiction would contain things that are conceivably possible in a technological sense (such as the spaceships, lasers, etc), but fantasy comes in when the supernatural elements (such as the Force) arise. Which would be why it is a split genre for that particular story. The original person mentioning it just reminded me of when it first came out and studios tried to market it as a Sci-Fi when all he wanted it called was fantasy. Then again, most people try to coin anything "futuristic" as possible and therefore science fiction and leave fantasy purely to the midevil knights and such.
