I've worked in communications electronics for over 3o years. I was wondering why this is neccessary myself. At first it seems that you are just extending a ground on one end like a long wire antennna to attract the lightning, thus bringing it closer to the house..
However I think this is what they are thinking.. You ground the messenger to the strand. Even though you use a bug nut which is made of higher resistance metal than a good grounding clamp, you are still placing the messenger closer to ground potential at the pole rather than the house, since the house end is open.. Therefore any lightning striking the messenger is going to travel towards the lowest ground potential which would be the strand, thus directing it away from the house.
Heres the specs
