Why would you think that?

"(b) If a vehicle is being driven at a speed less than the normal speed of traffic moving in the same direction at such time, and is not being driven in the right-hand lane for traffic or as close as practicable to the right-hand edge or curb, it shall constitute prima facie evidence that the driver is operating the vehicle in violation of subdivision (a) of this section."

Says nothing about limited-access divided highways.

That section has numerous exceptions, as does the referenced "subdivision (a)." The point is there are many valid reasons why someone would come to a dead stop in the left lane of a multilane 2-way road.

On a limited-access divided highway there are far fewer reasons, limited only to emergencies, and the left lane can be legitimately considered to be the fast lane.
