Traffic ticket given for incorrect violation?

So my boyfriend got a ticket this morning. The officer told him it was because he didn’t stay stopped at the stop sign long enough (however he did actually stop). The problem is that he wrote the ticket for failure to stop at a stop sign when that’s technically not what happened. That is important because in the driver’s law manual, there is no specification of time that you need to stop, only that you have sufficiently yielded to pedestrians and other vehicles. Exact wording is this:

“When traveling on a roadway that intersects with another roadway, if you are faced with a stop sign, but other traffic is not, you may proceed only after stopping and yielding the right-of-way to any other vehicle or pedestrian either in the intersection, or so close to the intersection as to make it dangerous to travel through the intersection.”

There were no other vehicles or pedestrians because it was 6:00 in the morning and his neighborhood is VERY inactive at that time. Therefore, it wouldn’t be required to stop for very long right?

This just doesn’t seem very fair to me, but is there anything that he can do?
