Pirate was stating that selling 10s of thousands of coins would not be possible without his lenders. Maybe some got scared to actually loose their coins if pirate just sells them all?
Of course, some people just saw a demonstration of what exactly their coins are being used for i.e. for selling them on mtgox. Not withdrawing it from pirate (if anything is there) would be at least unwise given the circumstances.
He said that a price jump was bad for him so I'm running away with my profit.
