No, it comes from maintaining other people's bad code for too many
years. It means, among other things, that all variables have acceptable
values at all times. By acceptable, I mean a valid value or a
pre-determined not-applicable value.
If I was writing the code in the example, it would be:
$station = $Station_for{$cli_station_code} || $NA{station}
or help( 'station', $cli_station_code );
Even if elsewhere:
our %NA = (
...
station => '',
...
);
The extra arguments for help() is to provide context-sensitive diagnostics.

Programming is as much about organization and communication
as it is about coding.
I like Perl; it's the only language where you can bless your
thingy.
