I think i have a basic misunderstanding when the module code is executed and the exported variable $_POST is initialized.

Directly after use YourModule; is parsed, perl search for that module, compiles it and runs its mainline, including the initialization of $_POST.

Minimal-ish example: 

$ cat A.pm
package A;
use strict;
use warnings;
use Exporter qw/import/;
our @EXPORT = qw/$_POST/;
our $_POST = 42;

1;
$ perl -I. -wE 'use A; say $_POST'
42
