What is the compensation if two Muwaddihah wounds are present, heal, and then the barrier between them is removed by the assailant?

Primary text

If the two Muwaddihah wounds heal and the barrier is subsequently removed by the assailant, the compensation due is the Arsh for three separate Muwaddihah wounds. This is because the liability for the first two injuries was established upon their healing, and removing the barrier necessitates the penalty for a third distinct injury.
