It's probably for "web seeds" or similar, where a torrent file's author specifies alternate URIs where the content can also be found. Transmission has no control over whether the torrent file's author specifies http or https, it has to allow both (and http is actually safe, since the downloaded file goes through the same piecewise checksum as if it were downloaded from a peer).
