I thought it explained reasonably well that it's an optical illusion. Sometime when the moon is up in the sky well above the horizon, stuck your thumb up at arm's length and compare it to the visible size of the moon. Then another time when it's near the horizon, do the same thing. You'll find that the moon is the same size relative to your thumb.
