It's the _perception_ of ephemeral, through the UI and the way twitter presents "real-time" (most recent first, difficult to scroll through older stuff, less than stellar search (at least compared to other services)).
Plus, there have been numerous documented instances where deleted tweets can still be found by Twitter's own search engine.
In short, the old rule of thumb still applies: if you don't want it archived and indexed and preserved forever, don't put it online in the first place.
