With SvelteKit, what will happen if I disable both ssr and csr?

In the doc, there's a comment in the code snippet, saying:

// If both ssr and csr are false, nothing will be rendered!

What does it mean by "nothing will be rendered"? In my understanding, ssr determines whether the page could be rendered from the server side, and csr determines whether the page involves JavaScript (thus is interactive). When I disable both ssr and csr, I think I will still get a static page, instead of a blank page or white screen. Is my understanding correct?

If I'm correct, then what does it mean by "nothing will be rendered"? Since I still get a rendered page. If I'm wrong, please point out what I have misunderstood?
