SPItemEventReceiver ItemAdded not firing

If you have configured ItemAdded event handler on a document library, and if you upload the same document multiple times, the first time ItemAdded event handler is fired. With the just uploaded document still in the library, subsequent uploading of the same document will not cause the ItemAdded event to fire.

I assume that SharePoint treats the subsequent uploading of the same document as an item being updated, not as being added, as in adding a new one.
