From the looks of it that only inserts the key, mine stores the values so that i can generate a new csv with the difference. This allows me to compare files with different numbers of colums and get the difference. For instance I have two reports, one with patient name and id, the other just with name. Now i don't loose that extra data after the comparison. Minor but in the cases I use it it helps a lot.
