Comment (by duck_):

 The problem you're facing is caching. wp_insert_term() will call functions
 to clear out the cache that stops the hierarchy displaying properly
 (clean_term_cache() -> _get_term_hierarchy()). So if you were to only add
 one term all would be okay. However, you're inserting multiple terms on a
 single page load...

   - clean_term_cache() contains some code, in the form of a static
 variable, to stop a taxonomy's hierarchy being rebuilt multiple times on a
 single page load.
   - because the code executes so fast the last_changed cache item in the
 terms group will not actually be changed on every term insert. Therefore,
 even if the above didn't occur, the result of get_terms() would be cached
 and only include the first term to be inserted (and any which existing
 prior) so _get_term_hierarchy() will return 'incorrect' information.

 I'm afraid I cannot think of a ''nice'' workaround right now.
