No. He's saying that clans have more commonalities with those they live closer to. Nothing more. Its like saying Habar Awal in the west have more in common with Gadabursi and Issa clans than they do with Issaqs in the East. There are micro-cultural variations among Somalis, even in Somaliland. This has nothing to do with kinship, its just a matter of proximity.
In my initial post, I said, "Buuhoodle and Boosaaso are the same ish. The same people/clan live in both cities.". My statement never had anything to do with micro-cultural variations, dialects and whatnot, which my friend Jugjugwacwac seemed to be hellbent on proving something that is irrelevant to my initial point. Furthermore, my initial post was also a response to a member that said the Somali refugees that arrived in Boosaaso from Yemen that were originally from Buuhoodle went to Buuhoodle. I said, there is no point for them to go to Buuhoodle, when Boosaaso is their home as well, due to both cities belonging to the same people/clan.
