The point is jurisdiction, not the ability to arrest and detain - those are different things. Simply breaking a law in another country does not make you subject to their jurisdiction and not that of your home country - you are first and foremost subject to the jurisdiction of the country where you are a citizen.
This would be jurisdiction over the subject matter, not necessarily personal jurisdiction.
