Postfix can reuse a connection if there is a lot of mail for a single destination. The destination might disconnect at some point, after which postfix is free to try again. Generally you can ignore this and it will sort itself out. If it doesn't sort itself out in a reasonable amount of time, you can configure delivery delays for that destination.
