Well, sure, because you don't assert it until after the engine stops
running.
If I put (run-until-halt) in CLIPS code, then

The same way that you would do two things at once in any Java program:
you need to explicitly do one of them in a separate
thread. run-until-halt (or the Java equivalent runUntilHalt()) never
returns, by definition; it's specifically designed to be run off in a
separate thread.
Of course, another alternative is simply to call run() again after
asserting the additional facts!
