As far as I'm aware, the reason for this is that the BitTorrent protocol is designed to share the user's IP with others in the swarm. Since Tor doesn't map each connection to a unique circuit, the de-anonymized BitTorrent connection could be used to identify other connections on the same circuit. The attack had nothing to do with large files.
