Sure. Getting 10x the resources for the same price is another valid way to express the thought. Saving 10x isn't, though.

I think you would be more accurate to say 'communicate the thought' as opposed to 'express the thought'. Communication carries the explicit desire to have an idea be shared. Expression carries no shared understanding and is personal.

The author expressed the thought in a valid way because we understood their words, but they did not communicate it well because we are confused about their understanding of those ideas.
