My expectation is that "set -e" won't prevent anything that comes
after "make sure we set CI_OS_NAME to osx on macos but do not do so
on other platforms" we see above from running.  In other words, with
a script like this:

    $ cat >X <<\EOF
    #!/bin/sh
    set -x -e
    CI_OS_NAME=linux

    echo different
    test "$CI_OS_NAME" = macos && CI_OS_NAME=OSX

    CI_OS_NAME=macos
    echo same
    test "$CI_OS_NAME" = macos && CI_OS_NAME=OSX

    echo both passed

    false

    echo at the very end
    EOF

I would expect all "echo" would execute, except for the last one
that is not reached because of the "false", which is the first
"2.9.3 list" whose last "2.9.2 pipeline"[*1*] yields a non-zero
status, would stop the execution.  Two 'test' before && may yield
success or failure and they may control whether the assignment to
CI_OS_NAME is done or skipped, but I expect that they do not affect
how "set -e" behaves.

    $ bash X
    + CI_OS_NAME=linux
    + echo different
    different
    + test linux = macos
    + CI_OS_NAME=macos
    + echo same
    same
    + test macos = macos
    + CI_OS_NAME=OSX
    + echo both passed
    both passed
    + false

    $ dash X
    + CI_OS_NAME=linux
    + echo different
    different
    + test linux = macos
    + CI_OS_NAME=macos
    + echo same
    same
    + test macos = macos
    + CI_OS_NAME=OSX
    + echo both passed
    both passed
    + false
