If you squirt yourself with water, you are saving the water inside your body from being sweat out because you don't need to cool down as much. You are not using up extra water, or running out of water you can't afford. One way or another, that water is going to get evaporated, this way just means you don't lose salt along with it, and you don't dehydrate from sweating.
I didn't miss the point at all. While water that you pour on you does cool you somewhat, it's not nearly as important as preventing dehydration. You
are using up water that you may need to prevent that from happening. There is nothing that will keep you from dehydrating except for consuming water. Like I said, if you have excess or a ready supply, pour away. But if you don't know where your next supply point is, drinking it is the best use.
