I thought that maybe the fact that you're using different shell processes
for the two parts of the expression might be the reason why it doesn't
work, but that appears not to be the case:
$ makepsres2; echo $?
bash: makepsres2: command not found
127
$ makepsres2 -q || true; echo $?
bash: makepsres2: command not found
0
$ (makepsres2) || true; echo $?
bash: makepsres2: command not found
0
Conclusion: I too don't see why it doesn't work.
Nonetheless, my suggested replacement is less obfuscated (ie, I understand
it ;-) and saves a few cycles too.
