Your creating a reference to an array as and storing that reference in array
index 0.
Data::Dumper can be very helpful for understanding what's going on here its
no different than doing saying $temp2[$cnt]  = \@temp1;

#!/usr/bin/perl -w
use strict;
use Data::Dumper;

my @temp1 = ("Apple", "Orange", "Mango");
my @temp2;

my $cnt=0;

$temp2[$cnt] = [@temp1];

print Dumper(\@temp2);

$VAR1 = [
          [
            'Apple',
            'Orange',
            'Mango'
          ]
        ];

As you can see here the first element index 0 in your array contains an
anonymous array.
I hope this is clear.
