This is a reasonably accurate reproduction of a Plains-style encampment and mini-powwow. The stereotyping isn't in how well the Russians emulate Indians. It's in their choice of focusing on the Plains Indians of the distant past.
As far as I can tell, these wannabes don't care about today's Indians. Or any other Indians except the ones they've seen in movies and on TV. Their presumption that Plains Indians stand for all Indians is what's stereotypical.
