I've just recently bought NX300 and I've found there are several Touch AF options:

I understand how "Off" , "AF Point", "Tracking AF" and "One touch shot" can be used. But there's one more option "Touch AF" when camera instantly autofocuses on touched area. But when I half-press shutter button to shoot camera auto-focuses there once again. What's the point of focusing twice then?

The touch focus allows you to choose what exactly the camera focuses on. Although it can be used like that, it is not intended solely to focus the camera. When it does focus twice, think of it more as initial trial run, to see if focus is possible. Also, if the lens is already focused on or close to a difficult to focus object, it refocuses much faster than if it were to try from scratch.
