This seems mad to me

I am playing in the G casino $40 feeder to tonights $200,000. 45 paid and its a rebuy for the first hour at $40. Main event is a $300 buyin. In the first 40 mins one guy at my table has rebought 21 times. I have busted him 4 times and when I left the table he was still rebuying. playing all kinds of hands, calling without made hands and doing a lot of obvious bluffing. yet his poker table ratings are good. Does anyone understand this stretegy. he could have bought into main event twice already
