After the prayer, deacons or other priesthood holders pass the bread to the congregation in a reverent and orderly manner. The presiding officer receives the sacrament first. The bishop (or a counselor in his absence) presides at the sacrament meeting unless a member of the stake presidency, an Area Seventy, or a General Authority is sitting on the stand. A high councilor does not preside and does not receive the sacrament first.
Even a very fertile bishop wouldn't need to pass the sacrament under these circumstances more than a few times in his life. I mean, how often does a Bishop have a son turn 12? I have a relative who has been a Bishop twice, and has seven sons, but even then he was only Bishop for two of his sons when they turned 12. So out of the 260 weeks that a guy's usually a Bishop, maybe once or twice he sits with the deacons and passes the Sacrament. Seriously.
Luckily, I live in an unusually perceptive and intelligent ward, and so we would probably be able to figure out that if we saw the Bishop stand with the Deacons and commence passing the Sacrament, he is probably satisfied that the prayer was said properly and everyone is worthy. He may have even delegated the prayer-monitoring duty to a counselor for that week, since he's allowed to do that. But I can understand that there might be Wards out there that couldn't figure this out and it might get a little confusing.
We even had a Sacrament Meeting once where the whole Bishopric was gone and the High Priest Group leader presided. I was worried about what might happen to the Ward members that couldn't figure out what was going on, and that there might even be some outbursts or trauma. Things went pretty smoothly, but like I said, we're a pretty smart ward, and we're quick to understand things like that.
