If he was injured, he would have been tied in and relatively immobile.
If those picks are James' (which is likely), the fact they were both out indicates he was healthy at the time, and using two arms. I believe he was on belay, and something happened to sweep the line down the hill with enough force to hurt him if his hand/arm was caught in a coil.
If they were on a long line, belay can last quite a while, so it is not uncommon to shelter the position and pull out your ground pad to sit upon while one belay... -Bruce
