Ok, i'm near the end of the script now. In this bit, I can see why the script prints out the line from $csv2, but I can't understand how it prints out the line from csv1. I can't see where it gets this information. 
 

if ($count >= $desired) {

      print "$csv2\n";

      ++$matched;

    }

  }
print "$_\n\n" if $matched;

I can see the: 
print "$_\n\n" if $matched;

bit somehow contains the information from csv1, but I can't see anything in the script which suggests why this would be?
