I find it hard to believe that the asymmetric design has optimal strength:weight ratio, which means it's not 100% eco-friendly. It looks like it's deliberately wasting material so it can have a distinctive shape that can be design patented, instead of a fully optimized generic bottle.
That's the difference between a freshman design project and an actual design used in practice. It's unlikely he has the mathematics/engineering background to do a proper analysis of his design.
He's not thinking of the bottle as a pressure vessel (which it is).
