I think you should mention "offline" in the description, e.g. "Label for the
button to show pages that have been saved offline."

Done.

Why "Mobile:" here and not on the string above? I'd just remove "Mobile:" unless
there's an equivalent desktop string that we're differentiating this string
against.

Also, referring to a string ID in the description isn't helpful since
translators don't see the string IDs. I'd say "Explanation for the button to
show pages that have been saved offline."
