the question is on whether Somaliland actually leaves, and if they do they can’t take lands that under PL. That is simply the reason why PL should be involved in any talks concerning territory that’s under its jurisdiction.
SL has already left, the only question is if it's gonna rejoin or if xamar is gonna accept it
anyways, even xamar has, during two administrations (HSM, farmaajo) said that SL consists of 5 regions and that eastern sanaag will be under SL, which i guess will be the case if the separation is recognized
i dont think that eastern sanaag will be relevant to such talks as that is a claim put forth by PL that's not recognized by xamar while xamar negotiates on behalf of PL and all other federal states
