Well, not necessarily. The idea being that you're planning to have it kick in at 5:00 for 10 minutes, but in order to smooth out the energy distribution levels, they push it to 5:10 instead, so you're still using your 10 minutes of AC, just at a slightly different time... That's my take on it, anyway.
