How exactly does that not work with browsers and local storage though? It seems like they're just caching stuff in the app and they definitely can do the same in browser storage.

On iOS, at least, local storage for web apps doesn't have guaranteed persistence. Safari can and will "randomly" clean up, usually if the device is low on storage. This happens less frequently for pinned PWAs but still happens.
If you need to absolutely guarantee that your thing will work on an offline mobile device, you have to use a native app.
