Listen the link below from Meles interview from 32:20
"Kezih alfo yehe meder Inwesdalen, yan mender InseTalen yehe ketema Inewesdalen yan ketema IneseTalen malet aydelem"
Badme and Alitena are " mender " while Zalambesa and Tserona are "ketema"as far as we now.
So Meles is telling us that "we are not saying that we will take Badme and give Alitena, or we are not saying that we will take Tserona and give Zalambesa". I cant see it in other way.
