Could you clarify what you are disagreeing with?

The methods that throw IE clear the interrupted status. If you catch IE 
then the interrupted status will be clear.  The guidance is to either 
(a) rethrow the IE, or (b) restore the interrupted status if you 
continue normally or abnormally (abnormally is throwing an exception 
that is not an IE). You could get unlucky and be interrupted again while 
handling the IE, so if you rethrow the IE then you would be doing so 
with the interrupted status set - this would be unusual of course, but 
possible.
