I've heard people saying sentences like

> 
> The rule applies to all the employees except for some exceptions.
> 
> 
> 

Doesn't the use of word "except" make it obvious, in this case, that they're exceptions? Shouldn't the sentence be

> 
> The rule applies to all the employees except for some.
> 
> 
> 

Is there any word for such sentences where a previously used word makes the latter obvious?
