Your remark is interesting! The doc says if they are some rules
defined in auto-beam.scm, you MUST use #(override and #(revert...
But only when the beam durations are the same. This is stated,
maybe
not very clearly, where I've indicated, here:
"There are two mutually exclusive ways in which these rules may be
modified. The first, modifying the grouping of beats, applies to
uncommon time signatures, i.e. those for which there are no
predefined
rules defining the beam end points. The second method, modifying
the
specification of the beam end points, can be used for any time
signature. This second method must be used for those time
signatures
and beam durations combinations for which beam ending rules are
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
pre-defined, unless these have all been reverted. There are
predefined
rules for time signatures of 3/2, 3/4, 4/4, 2/4, 4/8, 4/16, 6/8,
9/8
and 12/8. "
That's why the rules for 32nd notes don't affect 8th note beaming.
Also see the comment in scm/auto-beam.scm just above this
entry.
This was very unsatisfactory, but auto-beaming has changed
completely in 2.13, so the issue has already been addressed.
