No, it implements the bittorrent protocol like any other file sharing client. Just on top or more like next to it some other protocol is implemented that allows for searching, trackerless peer discovery, ... So you can leach from and seed to any other user of a client that implements the bittorrent protocol. Only the search, discovery, ... functionality won't be available to the other clients. Not exactly unexpected either as it's not part of the bittorent protocol.

Imagine you want to join some secret and private group. Members of the group share their contact data among each other. But being not yet part you're lacking that data and so can't get in. To initially get into the group/network, you need some starting point. Those superpeers are members whose contact data is publicly disclosed and if you want to join the group you get other contact data (Peers) from them. Again unrelated to bittorrent compatibility, just an extension.
