When you connect over the network a connection object is formed.
This remains (for efficiencies) between uses of sessions over that
connection. There can be only one connection between two machines,
so only one set of credentials in use. When you reopen Explorer and
navigate to the folder you are firing up a new session on the connection.
Use net use to see connections that exist
Use net use <device> /delete to end a connection

yes, it does. connection formation is relatively high overhead so they
do not get flushed right away
