what does that do

It has 2 positions. One is 1,2 meter and the other 3 meter. If You know the subject You are going to photograph is more than 3 meters away You can set the switch in the position 3 meter and save some focus time because the lens does not need to consider the distance 1,2 to 3 meters.

By limiting the range of the autofocus to 3 meters or farther away, the speed of focus can be increased. If the switch is set at the closer setting, the system has to consider nearer distances as well and that extra space can slow down the time it takes to lock on to the focus point. Most better telephoto lenses have this switch.

So if there was a stick in the air like 1.8meters away it wouldnt try to waste time putting it in focus or am i getting this wrong

If the switch is set to 3 meters thats correct.

Yes. Even if there is nothing there, the lens needs to rack itself in and out looking for the point that the focus is sharpest. It does not know that there is nothing close until it goes and looks. That wastes time that you can save by telling it that there is nothing inside 3 meters worth seeing.

Am I right in thinking it would good if you were taking shots of say motorsport through a fence which was really close to you (the fence that is) ???

Sounds like a #1 use for the feature but, in practice, if the AF sensor is covered by something too close, the camera will return an 'unable to focus' dot in the finder. I just confirmed this trying to shoot through a window. Whether this worked for your fence might be a question of how heavy was the wire and how accurately it covered the AF sensor in use.

Loved the idea!

Some very impressive photos so far!
This lens rocks, in spite of not using it as much as I thought I would. I'll just have to take the time to adust my shooting habits.

Some of mine:
