What confusion? People come and go every day at the Nuevo Progreso crossing with and without passports.
Do I have one? Yes. Do all my friends? No.
Not confusing at all, unless you want it to be.
The confusion is because people have been successfully indoctrinated to believe that travel documents are required when a US citizen enters the USA. Further, many probably have never taken the time to verify exactly what the law says. If a person was to write CBP, ICE, DHS, their Senator, their Representative, or even the President, the answer that is always written back starts with the same statement: "As a US Citizen, you can not be denied entry to the United States at any US port of entry even if you have no identification. You may have a delay as your identity and admissibility is verified."
Another part of the law states that your identify and admissibility can not be delayed. Once your identity and admissibility has been verified (barring any legitimate legal holds), you must be granted entry without any further delay. They should not be making a US citizen wait as punishment for not having their documents.
On average it takes less than five minutes for verification of a person's identity and advisability once at the counter providing information. Now I don't make it a habit of not having my documents but I'm not overly worried as it's not a big deal if I forgot it.
