Question related to Edward Snowden's book about using public Wi-Fi. [Contains Spoiler]

Dear fellow network engineers,

Edward is claiming that he didn't want to use public Wi-Fi such as Starbucks etc. because MAC address is being tracked and MAC addresses are unique(as we all know here). As we all learned, the traffic goes from hop to hop, the MAC address is being stripped and replaced by every gateway (own's mac address and its locally significant). Also MAC addresses are stored as in buffer memory of access-point and then flushed.

Is he trying to say that everything is stored permanently, or I am not understanding his claim?
