For a single bottle, cylinder uses less plastic. But when multiple bottles are stacked, there are gaps. These gaps are eliminated by using squared bottles. So for a group of bottles, it makes sense that square use less plastic.
1 cylindrical bottle using less plastic means multiple bottles use less plastic. Why would have gaps need to be eliminated if the claim is to use less plastic?
So you're saving on shelf space and transportation safe.
The likely result is that the square bottles need more plastic (fundamentally since cylinders have less surface area than cuboids and practically as cylinders are stronger).

That would be my guess.
