readme documentation wrong or confusing

in the **'Combine scopes with "OR"'** section it says:

```
User.id_or_age_lt_or_username_or_first_name_begins_with(10)
=> "id < 10 OR age < 10 OR username LIKE 'ben%' OR first_name like'ben%'"
```

Am I missing something fundamental? Where does the term 'ben' come into it? It doesn't even follow from the example above.
