Or, to put it another (hopefully better) way:
 
The mean sun was chosen such that the difference between its hour angle and that of the real sun is, on average, zero.

Noam,
 
actually, in a way, the equation of time curve _is_ symmetric around zero.
 
If you add the values of the EOT for all the days in a year, you get zero. You might say the integral of the EOT curve equals zero.
 
So the answer might be: legal noon was chosen such that the equation of time is, on average, zero.
