I tried making that alteration [see below] in
/opt/context/tex/texmf-context/tex/context/base/spac-ali.mkiv ,
but that didn't work. Was merely changing that file not enough, or
should I conclude that this fix does not work?

You have to regenerate the format (context --make en) when you patch a core file.
Just did so. The odd-page-invocations still fail. Does it work on your end?
There was a typo, this works:

\def\spac_align_flush_horizontal
  {\ifcase\c_spac_align_state_horizontal
     % 0
     \spac_align_set_horizontal_none
   \or
     % 1 center
     \ifcase\c_spac_align_state_broad
       \spac_align_set_horizontal_center
     \or
       \spac_align_set_horizontal_very_center
     \or
       \spac_align_set_horizontal_wide_center

   \or
     % 2 flush left

As an aside, on the page [[Running Mark IV]] the wiki says
"Starting with 2011, formats are automatically (re)generated by
`context myfile.tex` when it believes it is necessary to do so.", so
perhaps the format does not need to be manually regenerated. But
that's not relevant to this bug, directly.
The format is only auto generated when the version number is incremented
which does happen when Hans releases a new beta/current but not when
you change files.

BTW: The location key for \setuplayout is to position the page on the paper when the have different sizes.
Ah, so doublesided typesetting is activated from \setuppagenumbering,
not from \setuplayout? Thanks for the tip.
Yes, you need \setuppagenumbering to select between single- and doublesided document.
