Dying after reaching 30 stacks (150 autos) will cause Twin Cleave visuals to hang in the air during the second revolution while the hitbox is still created and deals damage as expected.
The logic to animate the second set of axe Actors still relies on Zul’jin having enough stacks, rather than his quest completion status. All these pieces are using ZuljinHasEqualToOrGreaterThan30TokensOfYouWantAxe.
