Ultralite 12.0.1 for iOS

When I synchronize my ultralite database, i'm performing it on a background thread using the shared connection I created when the database was initialized:

dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0), ^{
     //Synchronize with Mobilink on shared connection created when DB was initialized
     [self synchronizeWithConnection:sharedConnection]
});

According to docs:

Multi-threaded applications
Each connection and all objects created from it should be used by a single thread. If an application requires multiple threads accessing the UltraLite database, each thread requires a separate connection.

Because I am synchronizing on a different thread than my original shared connection I make when I create the database, should I create a new connection to the DB on each sync, then close the connection when sync has finished like such?

dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0), ^{
     //Get a new connection on the current thread
     ULConnection *newConn = [self getNewConnectionOnThisThread];
     //Sync on the new connection
     [self synchronizeWithConnection:newConn];
     //Close out the new connection
     [self closeConnection:newConn];
});
