This wording seems off, and we could probably improve it and make it friendlier to JS (which doesn’t have namespaces) at the same time. I think it means that an import declaration has to be at the top level of the file.

That's how it's implemented, yes. Well, it also checks for parents like namespace N or declare module "m", neither of which apply to JS.
I'll open a bug proposing to split the current implementation into 2 messages and improve the wording.
