Why is that material to this discussion? Because it illustrates that the FAA doesn't set the carry on rules otherwise they would be the same for all airlines. The FAA just states that the airline has to have a plan and follow it.

You, nor I, know what US's operations specifications state. So for you to say that US isn't following the policy is based on your assumption that their operation specifications state that all passengers, including crew members not working, are restricted to 1+1. While it is certainly possible it says that, I would think it is highly unlikely.

There are many reasons why an airline would allow its employees to carry on more than 1+1 so it is likely that their operations specifications specifically state this.

Lastly, as often as it happens, there is no way that it wouldn't have come to the FAA's attention in some way and that the FAA would address it, and we'd hear about it if it were a violation.
