Well, He both died and didn't die. He died because His divine nature was united with his human nature making Him just one person. He didn't die because His divine nature cannot experience any death. In other words, He was both an authentic human and authentic God.
Spiritually speaking, ultimately there is no death because our souls do not die. So, dying to the flesh, the world and death itself is actually the most life giving experience because we awaken to the reality of our indestructible soul. Death is rather the (tormenting) state of a soul who does not live, but that soul continues forever.
