You won't be copying the same file. When you use calibre to copy a book to the device, calibre first creates an updated copy of the book with the newest metadata (tags, etc). It is this copy that is put on the device, not the original.

The original does not contain metadata corrections. Those are in the calibre database.

And another quick reason. Calibre does not remove problems. Let us say you notice a typo in a book title - so you change it. If you then send out that book to your device, you will now have that book on the device twice. A more common reason is that you notice the Author/Title fields are back to front. So you fix it. What is now on the device??
Two copies. This is by design. Some people would be most unhappy if calibre started deleting books off their device without some explicit request on their part.

I do understand the issue, but I haven't been able to find a way to 'clean' without running the risk of cleaning too much. What I am doing now is looking for a way to distinguish between the copies to make finding the one(s) to delete easier. Perhaps a modified date in the device view would work?

(Edit: There is a date in the device view. It is the date the book was put on the device, not the date the book was modified. Perhaps this is good enough?)
