I think the check is to ensure the passed index parameter is to verify the boundary of text length.

If the `index` is equal to the the `text length`, the returned character from the `getBeforeIndex` should return the last character i.e. 6 but the existing condition evaluates to `true` due to `index equals to model.getLength()` and method returns `null`. So, even the `direction` is handled correctly below, execution doesn't reach to that point.
