Look at it as if there is a pulley where the chain changes direction. A force is created in the chain as each link is decelerated by the stationary section that adds to the force of gravity. So the acceleration of the end of the chain is greater than just the force of gravity would create.
If the anchored end of the chain was connected to a fish scale, you would see that as the chain drops and folds back on itself, the force read on the scale would be greater then just the weight of the chain. This same additional force is applied to the dropping weight through the virtual pulley created by the joined links where they change direction.
