I'll just throw this tidbit out even though it sounds like in this specific case gold is physically moving.
But in many (most?) cases, gold in these amounts is held in very few physical locations around the world, like The Bank of England, and "moving gold" just means changing paperwork on who "owns" which gold inside the vault.
