I believe youre seeing an artifact of how governance is divided. It looks like sweden (and many other parliamentary systems) puts the administration & execution of law under the direction of a minister, who’s primarily a legislator.

In the USA these areas are more clearly divided. The federal legislature is comprised of a bicameral house and senate. There is a discrete executive branch charged with enforcing the law set by the legislature. The president is the head of that executive branch who enforces those laws. Thats where the aspect of specific enforcement by the president comes in.
