In that case, I'd expect to find a few beads in the middle.
In any case, clearly the prevailing understanding is wrong in one way or another, and that should be reflected in curriculums alongside this new evidence.
But it really wouldn’t surprise me. As others pointed out, the Inuit traveled across the Bering Strait into what is now Russia many times pre-Columbus, so the idea they may have brought beads back with them is plausible.
