Sort of, you're making more that one connection, so if you have 3
connections to the same publisher, you'll get the message three times. When
you do the resubscribe, you actually subscribe both connections. So even
though you've unsubbed on the first one the filter gets replaced, and you
have 2 connections with 2 valid subscriptions, so you get the message twice.
