If you mean the gentleman at the top of the thread, no, his posture is not "normal"; and the excessive angle of the mandolin does get in the way, distorting all the angles, that of the right forearm, that of the left arm, wrist, and hand. It really detracts from his playing.

In fact, there has been a trend (discussed at length elsewhere) among players of the "Modern Italian School" (i.e. post-Anedda) to play with the mandolin more horizontal than was common earlier in history. That discussion belongs elsewhere, not on this thread; suffice it to say, however, that too vertical an angle (for the mandolin) is not seriously advocated by anyone I know of.
