-In this example, the module `quux` re-exports all of the public names defined in `foo`.
+In this example, the module `quux` re-exports two public names defined in `foo`.
 
 Also note that the paths contained in `use` items are relative to the crate root.

+So, in the previous example, the `use` refers to `quux::foo::{bar, baz}`, and not simply to `foo::{bar, baz}`.
 This also means that top-level module declarations should be at the crate root if direct usage
 of the declared modules within `use` items is desired.  It is also possible to use `self` and `super`
 at the beginning of a `use` item to refer to the current and direct parent modules respectively.
