If this is the first repetition, it returns true.  Otherwise, if the 
value of 'name' is different in the current and prior repetitions, it 
returns true.  Otherwise, it returns false.

This is why it needs a sorted sequence -- it only compares the current 
and prior values, which only works if the values are already sorted.

That would probably be better handled with ZTUtils.Batch and a Script.
