What's the significance of the declared name being in scope in the else
clause here?

else is a part of the if statement. Everything under the statement
should have visibility to its lexical variable(s).

Otherwise, code like this is prohibited:

  if (double x = fun(y); x < 0)
    return x * x;
  else
    return x * y;
