Due to the fact that in LT-Seeding protocol resources are being identified using a hash value that is being calculated per file this means that through LT-Seeding you could even get the same files from peers belonging to another torrent swarm (i.e. a torrent swarm using a .torrent file with a different info-hash than the BitTorrent swarm for which you're currently being a peer), as long as at least some files of the alternative torrent are identical (on a binary level, thus yielding the same file-hash) to the ones of your current torrent and LT file hashes have been uploaded to the server for those files.
