Priority ties happen for example when people get "disconnected by peer" aka ISP provider ; you connect, and you can see your ghost.
Unfortunately as he has the same resource as you he's discarded (or it seems).
In that case, sending a message to both resources means only one gets it.

They also appear when wanted explicitely.
One could expect that getting the message on the destination boxes is wanted.
In my case, it is.

Apart the "sell 50 shares" reason (which I find not quite good since the messages have timestamps on them) I don't see what's opposing this practice.
Anyway, if the "sell 50 shares" effect is a problem, we could do something : also broadcast the someone-using-the-multiple-jid messages to the other resources with same highest priority.
Maybe it's too complicated... 

My 2 shares...
