Yes, I agree ... it's somebody's idea of a bonding system. With those small wires, they may be useless. What do you mean by "heads forward and meets up to a metal post". Is the post connected to something like the mast base or the stem fitting? Is the "post" a rod or screw terminal strip or a chainplate of some sort? If the wires are connected to chainplates and/or the mast, it seems like it may be a useless attempt to protect against lightning. I'd be inclined to strip it all out and do some research to figure out what I want to replace it with, if anything. There looks to be some corrosion going on in the wire terminals anyway.
