Loopback interfaces are up constantly and the BGP session may need one interface constantly up to stabilize the session. The neighbor update-sourcecommand is not necessary for directly connected internal BGP sessions.

Neighbors are sorted according to the source and destination ip addresses. If an update-source ip address exists, then the source ip address determines the order in which the neighbors are displayed.
