I suspect this is a Windows behaviour rather than anything that iTunes is in control of. What behaviour do you see if you make as if to drag and drop onto another application?

BTW this is drag/drop to the iTunes sidebar. The icon behavior during drag/drop is clearly the responsibility of the app, in this case iTunes.
Dragging/dropping the same files on Windows Photoshop or Premiere Pro CS6 shows "copy" on the drag/drop icon, and a plus sign. The drag/drop modifiers CTRL, ALT and SHFT do nothing, which is appropriate for this case. The drag/drop icon behavior is different within Explorer (see below). The individual apps control this.
On Mac OS X 10.8.4, drag/drop from Finder to the iTunes sidebar shows the file icon. If you press Option, it changes to a green plus sign. In both cases the actual operation is a copy. You could argue this is inconsistent since the file is copied in both cases, but at least it's not outright wrong.
In some cases the documented Mac OS behavior for unmodified drag/drop is create an alias, and pressing Option is required to copy the actual file. http://support.apple.com/kb/PH11365
It appears whoever wrote the Windows iTunes UI event handling for drag drop implemented the above logic for icon display, but the actual operation was a copy, not create an alias or a link.
Windows iTunes shows the wrong icon during a drag/drop from Explorer to the iTunes sidebar. It says "link" but it's not creating a link, but copying the file. Unless there's some non-intuitive rationale for this, it appears to be a gross error. It's not an esoteric rare operation but in a common user path. This is the equivalent of misspelling a word in a newspaper headline.
Background: dragging and dropping from one Explorer window to another has the below behavior, which is by design and the responsibility of the app (Explorer):
Within same drive: move. Indicated by: "move" on the icon and a single straight arrow.
To different drive: copy. Indicated by: "copy" on the icon and a plus sign.
These operations are modified by these keys during drag/drop:
CNTRL: changes move to copy. Indicated by "copy" on drag/drop icon, and a plus sign.
ALT: changes move to create link. Indicated by "create link" on drag/drop icon, and a curved arrow.
In all cases the icon shown during drag/drop should accurately reflect the executed operation. That is not happening on Windows iTunes.
