This is the same as a removed member still having their browser cache containing team data. The advantage of this design is you get an app that is extremely responsive and offline capable. Then you just need a reliable way to sync changes. And you always have the option of just re-downloading the entire team db again if it gets corrupted somehow. You could even have logic to indicate the sync status of each table so that you don't need to download the whole table...you could just populate it as your need the data...like a cache.
