Hurley and Sun came together on Ajira 316. Hurley was on the plane because of what Jacob told him, so the flight of 316 occured after Jacob was seen alive with Hurley. Sun arrived on the island in the present; Jacob was killed shortly after she arrived. By the transitive property, Jacob's meeting with Hurley was not after he died. He is not still alive. One did not occur in 2008 and the other in 2007. Jacob died about a week after talking with Hurley.
