JavaMemoryModel: Store/load barrier

Please excuse me if my quesion is naive. Does new Java memory model require a store/load barrier between dynamically successive unlock and lock operations on different locks? According to JSR-133 Cookbook it does but I cannot figure out how this follows from the happens-before relationship defined in the memory model.
