\set and \unset are commands setting context properties at the current
point of musical time in a context.  Here you are both setting and
unsetting a property at the same point of time.  The net effect is zero
since the code dealing with setting/resetting properties runs only once
per timestep, and the code dealing with \clef bass is not wedged in
between.
