These look like change outputs after 4 separate withdrawals of 250 BTC from the hot wallet. It could be they split large amounts up into smaller amounts to save on fees, or perhaps they transferred coins to the cold wallet in pieces of 250 BTC. Maybe they deposited to MtGox in 250 BTC pieces. Either way, each of those 4 amounts is the change from sending 250 BTC elsewhere, not a deposit to the hot wallet.
