The comparison with an engine wasn't a joke. The heads get parked even
without electric power by the moving plate. The reason to wait is
probably not to avoid a pre-ignition/delayed ignition alike effect, a
more apposite comparison, before switching from forward gear to reverse
gear the rotational frequency should be zero ;). However, even this
analogy isn't perfect, since there is no gear involved.

While the move in the wrong direction is a joke/myth, it's true that old
small mopeds had only a single ignition point for all speeds and it was
possible to adjust it mechanically. I forgot that motors these days are
controlled by microchips. Adjusting an ignition point mechanically is
from the times when dinos and Neanderthals used tape cassettes. A tape
cassette is a kind of USB stick alike thing to record music.
