-In this example, the registered hooks will form chains. If both `first.mjs` and

+In this example, the registered hooks will form chains. These chains run
+last-in, first out (LIFO). If both `foo.mjs` and `bar.mjs` define a `resolve`
+hook, they will be called like so (note the right-to-left):
+node's default ← `./foo.mjs` ← `./bar.mjs`. The same applies to all the other
+hooks.
 
 The registered hooks also affect `register` itself. In this example,
-`second.mjs` will be resolved and loaded per the hooks registered by
-`first.mjs`. This allows for things like writing hooks in non-JavaScript
-languages, so long as an earlier registered loader is one that transpiles into
-JavaScript.
+`bar.mjs` will be resolved and loaded via the hooks registered by `foo.mjs`
+(because `foo`'s hooks will have already been added to the chain). This allows
+for things like writing hooks in non-JavaScript languages, so long as an
+earlier registered loader is one that transpiles into JavaScript.
 
 The `register` method cannot be called from within the module that defines the
 hooks.
