Decision has to be made by Point

This time Point is wearing the GoPro between his ears. All in all he is much more restless with his head than Moritz, but this is his character. Besides he runs free.
The snippet happens at a parting of a ways, all in all 5 different paths are leaving.
In between he is scratching his mouth at his leg.
First he walks in front, than we overtake in his back and he follows.

After seeing this video a lot of people say that the scratching seems like a displacement activity.
