Andrew, I asked the same thing of Scott and apparently the memcached client will generate a hash from the data to be stored and will use that to determine which of the configured servers to send the information to. We are using the memcached registry too, however I haven¹t sat down and dug into the memcached client code to figure out either, but that would be my recommendation if you want to know what is going on.
