If the torrent client is on a box behind a NAT on a private IP address,
and it is firewalled in such a way that only tor traffic can exit the
box, there is no way the torrent client can possible obtain the external IP.

Nonetheless, there are other reasons why one should not use bittorrent
over tor, not the least of which is that it is a bandwidth hog.
