No it does not mean terminated by signals.

In that case, why not just use another code instead of the code that
leads misunderstanding? I mean, as far as I know, exit code between
129 and 255 are used to indicate the program terminated by signal. So
that usage function can only exit with code between 1 and 127. Am I
wrong?
