Hm, that doesn't directly address something like

  set -e; true && (false; echo one) || echo two

If the subshell should execute "echo one" then the parent should not "echo two".

Unfortunately I don't follow how any of the POSIX.1-2024 text is meant
to apply to

   set -e; true && { false; echo one; } || echo two

Is "false" there considered to be "any command of an AND-OR list" ?
