Hotline,

Just to answer your post and to repeat what I said before. I agree with you and Bill, that more than one point of bonding would be better. However I have to enforce the NEC as written. I can't make up my own rules, so if the second cup is effectivly
"bonded" together with the first one with bolts and nuts, then I guess I would have to pass the job. Not that it is the way that I woud do it.
