hey,

the superNET IPO was uncapped, so it needed a replacement called Token to determine how much superNET assets will be created at the end of the IPO.

If you have Token on Bter it will be exchanged to Unity (trading symbol of superNET asset) through a automatic process.
Else if you have Token on NXT AE you have to go through the process described in the OP of this thread. (This should be done as fast as possible)

so what you see there are actually the not yet redeemed tokens. you could buy them and redeem for the supernet asset or directy buy the supernet asset.
