It couldn't.

Or possibly list its contents twice, in two namespaces..

Yes. hidden=no, list=yes configuration breaks the "list doesn't cross
namespace boundaries". That's why I said it's arguably wrong to use such
configuration.

With hidden=no, list=no it works the way namespaces were intended to
work, but few clients show the namespace's contents then. That's why
Mark was talking about his chimera namespace (which is similar to
Dovecot's hidden=yes, list=yes namespaces) and the idea of maybe getting
rid of namespaces completely.
