Yes, it should.  You've identified a weakness with the current autobeaming
architecture, which uses beaming groupings to determine measure grouping.
An improved version is currently in preparation.

But as long as you aren't using the Measure_grouping_engraver, the simplest
way to get what you want is just use

\overrideBeamSettings #'Voice #'(3 . 4) #'end #'((* . (1 1 1)))

Thanks,
