Point of Interest "Towards POI" button?

[Badgersurfer]

I used the POI Intelligent Mode today for the first time and it was fairly easy to work out BUT at the end of the setup I got this button saying "Towards POI". I am not sure what it did as I saw a start button and pressed it and all looked fine. I did **** it up the first time as I didn't realise you had to manually trigger the video record. But I cannot seem to find anything explaining the "Towards POI" button?

"Towards POI". keeps the camera pointing towards the subject.
You may want to fly round something and show the view from the subject rather than the subject, in that instance you wouldn’t use towards point of intrest.
