In general, that is a bad idea. In very simple terms...
You want the water to soak into the ground. The deeper it goes, the less will evaporate. So more will be available to the grass\plants. That encourages roots to grow deeper.
The 3rd watering is to add even more water because plant demand has exceeded the deep soil reserve.
One easy way to decide for yourself is to ask what if you broke the times into much shorter lengths, but ran it daily. Much of the water would evaporate. Roots would be only at the surface. The ability to survive a missed watering day would be very poor.
