Visible smoke not a possibility. First, it is called smokeless powder for a reason. Second, it is being ejected from the barrel at the speed of the bullet (~1000 feet per second), or even faster from rapid expansion. The case is moving much slower than the bullet. When shooting, it is common to be aware of the case motion (sometimes it hits you in the forehead). I have seldom been aware of smoke from an immediate shot.

You have an imaginary conception of what the proper shooting stance should be, and there is nothing about his stance that is contrary to proper shooting posture. Relaxed is a good way to be. Being tensed up leads to a poor shot.

The cameraman was lucky to get the shot, but being lucky does not mean impossible.
