When using Express SDK, what problems occur if different clients log in to a room with the same userID?

If different clients use the same userID to log in to any room:

• The client user who previously logged in with that userID will be kicked offline and receive a notification of room state change through the onRoomStateChanged/onRoomStateUpdate callback; the streaming and pulling in the previously logged in room will be stopped.
• Other users in the room will receive a notification of room user change through the onRoomUserUpdate callback.
