This is a question from sentence correction.
Incorrect: The possibility of an attack on Indian Point, a nuclear power plant, has caused local governmental officials to plan evacuation routes, build shelters, and offering citizens potassium pills so there will be fewer casualties in case of a leak.

Correct: The possibility of an attack on Indian Point, a nuclear power plant, has caused local governmental officials to plan evacuation routes, build shelters, and offer citizens potassium pills in order to have fewer casualties in case of a leak.
The word "offering" is changed to "offer" in order to make the sentence parallel.
But I don't understand the reason of changing the phrase from "so there will be" to "in order to have". Can anyone explain me the reason? If I retain the first as it is, will the meaning remain the same?
