I'm guessing that the part we are missing is the tag on R1 while still in contact with the base. It wouldn't surprise me to hear that USSSA doesn't consider that forced runner in jeopardy while still in contact with the base; so their ruling might be only the BR is out, and R1 and R2 are still safe on the bases they never left.
