Yes. Exactly.
It's not about offline apps, it's about reducing loading time.
Prefetch manifest is a way to tell browser what should be downloaded in advance.
So when user opens the site (for the first time) all resources (css/js/images/...) are already cached.

And if later site's resources are updated browser could check prefest manifest and
re-download all new resources in background. Before user visited site again.
