My view of this "problem" consists just to assign a weak directionality to the boustrophedon text, so that it will
inherit the direction set by any text before it (the transition from strong directionality to weak directionality
implies no required change of baseline direction, and will cause no additional line break). But anyway it remains
to restore the correct direction for the text that follows the boustrophedon part, because there's a transition
from weak to strong directionality (and even in this case, I don't see why this transition, implies a required line
break after the boustrophedon part, it will just require a change of direction if appropriate, depending on the
direction state of the last boustrophedon characters). And of course this is independant of the fast that the
Boustrophedon part will mirror (or not mirror, depending on the type of boustrophedon style used) its glyphs when
its baseline direction changes between pairs of lines.
