Can you elaborate on this...higher then the shoulder based on the horizon, or higher based on a linear path between the shoulders....
As Einstein said, it's all relative.
It has nothing to do with the person's orientation relative to the ground.
Instead, what matters is what's going on relative to the other anatomy of the shoulder. The reference point that I use is the top of the Acromial processes, which is the bony bump at the top of the shoulder. Another reference point is to draw a line perpendicular to the spine at the base of the neck.
Because of this, interpreting whether someone's elbows are above the level of their shoulders can get a bit tricky. I have personally been fooled by guys like Dontrelle Willis and Randy Johnson who lean forward during their stride. That can make their elbows look higher than they actually are. Their elbows ARE high relative to the ground, but that doesn't matter. What matters is that they are below the level of their shoulders.
The photo below of Randy Johnson is a good example of this. Notice how he's leaning forward toward 1B. That means that while his elbows are high up in the air, they are still below the level of his shoulders (as measured by a line perpendicular to his spine whose origin is the top of the neck of his jersey).
