The two tools access different GDS systems and through different means. ExpertFlyer access it's GDS's directly under contract. Also, different GDS's will load the same inventories with different maximums indicated. Sometimes it is 9, sometimes 7, sometimes 4. Another variable is how often the airline updates the data it loads into a GDS. Some airlines, like AA, are realtime in Sabre and any changes are reflected virtually instantly.
