When a connectionloss happens all the watches are triggered saying that
connectionloss occurred. But on a reconnect the watches are reset
automagically on the new server and will be fired if the change has already
happened or will be reset!

Yes. That is true. In particular, your link to a server (or the server
itself) can fail causing your client to switch to a different ZK server and

I think that the difference between connection loss and session expiration
might mess you up slightly in your disjunction here.
