Is the car overtaking the moped correctly?

The no-overtaking sign indicates the prohibition for all vehicles to overtake motor vehicles travelling on the carriageway, unless they are two-wheeled motorcycles and provided that the area reserved for the opposite direction is not invaded, from the place where the sign is located until the next "End of overtaking prohibition" or "End of prohibitions" sign. Placed in those places where overtaking is prohibited by rule, it generically reminds of the prohibition to perform this manoeuvre.
Therefore, the overtaking is correct since it is being done to a moped, which is not considered a motor vehicle, and it also respects the lateral safety separation of 1.5 m with it.
