 Nope, it's the opposite. :)
 You don't redirect "stdout", you redirect only fd 1. fd 2 is unchanged
by the second redirection.

 prog  --1--> "stdout"
      \--2--> "stderr"

  | exec 2>&1
  V

 prog --1--\ /-> "stdout"
     \--2--/

  |
  | exec 1>foobar
  V

 prog --1--> foobar
     \--2--> "stdout"
