It should be if it matches or is greater.   For example, if it was the very 
last entry in the DB, thus the last to be added to the resulting LDIF, it 
is entirely possible that multiple modifications could be done from the 
time the dump started and the dump ended, meaning the CSN would be greater 
than the one encountered in the accesslog DB.
