One of the things that I and those that learned to dive wrecks with me,
learned was not to make things more complex than they have to be.  Thus,
the direction things are twirled became more complex than simply
remembering that the end that came loose from the wreck last (when
untwirling) is the way out.

This comes from the fact that it's easier to twirl the loose end around an
object than it is to twirl the end that's already attached to (an earlier)
piece of the wreck.
