Yes it happens when an incarnete dies during it's turn, but only if the next in line is a player controlled character that didn't summon it.
Not sure what giving you a save of it is going to do for you, it's not something that is guaranteed to happen when you replay the fight.
But if you REALLY want a save of it right after it occurred and one at the start of the fight, then sure.. I'll make them for you.
