Kimimaro Kaguya has two dots on his forehead. In South Asia, it is called a *bindi*. Is it an identification mark, or does it have any significance like a curse mark? Is there any canon reason given for it?

I came across a source which said that it represents his clan, but the Kaguya clan doesn't have significant history in Naruto/Shippuden anime or manga. Is there any source for this claim?
