What would be the point of spraying someone in the face like that if it was not "real", just spray a target if the training was for the aiming of the spray.

This is more than likely what most LEO have to go through as part of qualifying to carry OC spray and that is to be sprayed yourself. I have never been sprayed with the foam, only the stream because that is what I carry but I would imagine those officers who do carry foam would be required to get hit with it.
