I personally like that angle, there are definitely good shots forward too, but unless you are doing something real exciting, forward shots can be boring. The type of riding in this video, what looked like mostly flat ground, a forward shot would look boring, just terrain tipping left and right if you could even see it due to the amount of snow. So if you wanted a vid of this ride, what is provided here is the most exciting IMO - unless of coarse you have a video crew following you and coordinating with you. Since i'm not an extreme rider (drops / jumps etc), the most action is me moving my body.
