False. An operation can only affect one entry. An entry has only one CSN 
(entryCSN is single-valued). Multiple changes may have occurred to an entry 
before a consumer sees it, but the consumer will only see the final result and 
only the last entryCSN.

On the other hand, multiple CSNs may have changed in the cookie that is 
transmitted to the consumer. That's a separate issue...
