That makes sense. The following movements just seem unusual. On Nov 15, 2014 they were moved again, to 4 separate addresses. And on Nov 28, 2014, these 4 addresses were all spent in different transactions. And on Dec 2, 2014, once again all were spent.
The Bitcoins that are due to be returned through the Kraken might have been moved out of MtGox addresses after it closed. The courts or liquidators might have moved them to new wallets to ensure Mr Karples couldn't control them anymore. They wouldn't be stupid enough to leave them in addresses controlled by him in the past.
