Yep. The theory makes perfect sense, but it's still interesting to watch
the f/2 signal appear from nowhere like that. You expect behavior like that
when you're playing with tunnel diodes or other unusual parts, but not with
an ordinary mixer and filter.
Even a regenerative receiver gives some warning when it's about to break
