I'm actually not convinced that he's reaching out to catch the falling mic. To me it looks more like Paul McCartney is running by, touching him and he reaches out as a reaction to that touch. The mic then just happens to fall into his arm. But that's just my interpretation. Also, a life music concert is incredibly loud. I think even for a trained man it would be extremely difficult (if not impossible) to hear the falling microphone. I find the cane against curb example much more realistic.
