No weirder than hanging an American flag outside one's house. "Oh don't mind my little totem there. Yeah, no, I'm too tribal to recognize the absurdity of this practice."
...let's pretend you are just a simple totem believing tribalist. Things become so bad in your own tribe that you leave, despite worries as to whether another tribe would ever accept you as one of their own, much less even accept you in.
Thankfully, you find a tribe that is willing to take you in.
After some time you decorate your hut with your last tribes totems and tattoo your children with the old tribes symbols.
It may be an over-simplification but it is more universal or common than you might think. I recently discovered that my father's entire family emigrated from their home country as a result of political persecution. This is a pretty common theme in American history. In fact, much of the progress and greatness of the United States was built by immigrants because of the opportunities this country gave to them.

See, it doesn't make any sense either way... IMHO
