Story : Seller bid for his own ...bidding..!!

Seller is irox
Co-Seller is jk

People start to bid...then suddenly this "special " bid come in...


Question :

How come co-seller can bid for his own selling ?? By right , irox & jk both cannot bid at their own thread ...so, is this a mistake or ??? Another mystery is that if co-seller have his own account, why can't he sell on his own , why still his friend - irox to help ? I just cannot understand

Update:
Seller jk finally sell his card on his own...
