Runner on first and third, and the runner on first steals second. The runner on third goes home on the throw to second. Is the runner on third credited with a steal?

I have always scored it a double steal.
Per 10.07 (c)
(c) When a runner, attempting to steal, or after being picked off base, evades being put out in a run-down play and advances to the next base without the aid of an error, the official scorer shall credit the runner with a stolen base. If another runner also advances on the play, the official scorer shall credit both runners with stolen bases. If a runner advances while another runner, attempting to steal, evades being put out in a run-down play and returns safely, without the aid of an error, to the base he originally occupied, the official scorer shall credit a stolen base to the runner who advances.
