Yes, the user 14512843168518#devchat.drooly.co had an open session with resource androidjc1PGFLG, and this session was terminated and replaced by a new session with the same resource.
This is a feature of XMPP: if a user's client has lost its connection to the XMPP server, but the server hasn't detected it yet, the client can force the server to terminate the previous connection by connecting again and specifying the same resource.
