The original uploader is only notified of Reseed Requests if their torrent client has reported that it has downloaded it in full from the tracker. Whether this has happened or not will depend entirely on whether you seeded the torrent correctly in the first place. If you did, then you would not be notified. If however the original uploader registered with the tracker as a leecher, then their name would be added to the list, and as long as they are not #121 or higher on that list AND their account is still active, they would then get a notice also.
