I agree. A pitch and a summary are different. Part of the art of the one-sentence description is knowing your audience. For instance, I operate a directory of technology for teachers. One of the services I provide is a newsletter and blog [1] where I summarize technologies (e.g. websites, mobile apps, desktop apps, electronics products) in one-sentence descriptions. The way I've written those one-sentence descriptions has evolved over time. The format that has resonated the most with my audience is stating the technology's primary purpose, which sometimes can imply it's benefit. Since I know my audience is teachers, the context of the purpose and benefit is already assumed and baked into the description. I would never use a "This is X for Y" description, for example, not because I dislike it (which I don't), but because it wouldn't be informative for my audience. However, I think a "This is X for Y" description can be entirely appropriate for an audience of startup investors. This is why YC coaches their startups to use such a sentence framework.
