As witness SpaceX's reporting on the engine explosion a year ago, you need
to read their statements about mishaps *very* critically, with careful
attention to exact wording. E.g., last year they said (roughly) "the
control system noticed falling chamber pressure and issued a shutdown
command to the engine"; they did *not* say "the engine was still running
properly until it shut down on command", but many people jumped to that
conclusion. I expect this was precisely their intent.
I find it interesting that this time, they keep saying "rupture" instead
of "explosion"; this strikes me as odd but I haven't yet spotted what
conclusion it's meant to make me jump to. :-)
