If you add
\context { \Score \remove Timing_translator }
to your \layout in both of the above snippets, the reverse situation occurs.
It seems to me that the "normal" thing would be to remove it; somehow
it seems logical that the barline engraver would use the info
generated by the timing translator to decide where to place barlines,
so the barline engraver should be last.
I'm *guessing* that if not explicitly removed from Score, there will
be TWO Timing_translators going in parallel, creating some sort of
race condition?!
Taking the example from the docs and commenting out \remove
Timing_translator also messes things up.

Right now I'm not sure that I *do* have anything valuable to add, at
least not in terms of writing a concise description of the situation
for putting in the documentation :-/ (though I still think there ought
to be one)
