But you did not pass \beamExceptions a bar beamed as you would wish.
You passed it a bar with beaming depending on a combination of automatic
beaming and beaming exceptions.

That doesn't work since at the current point of time, beaming exceptions
_only_ affect beam ends.

Beaming for 1/16 notes ends here after c''16] and nowhere else.  Beaming
for 32nd notes ends after g'32]) and a'32]) and nowhere else.  Those are
the beaming exceptions being generated by

\beamExceptions \barOne

as you can verify with

\void \displayScheme \beamExceptions \barOne
