Perl - With overriden method avoid super() is called

I'm trying to create the abstract method pattern using Perl and Moose. What I don't understand is that if I override a method from the AbstractClass it will eventually be called anyway. Why is this and is there a way to avoid the superclass from being called?

Main

package main;
use AbstractSort;
use OrderedSort;

# Sub class test
my $ordered = OrderedSort->new(array => [1, -1, 23, 34123, -24324]);
$ordered->sortData();

AbstractClass

package AbstractSort;
use namespace::autoclean; # Trims EXPORTER 
use Moose;

has 'array' => (traits  => ['Array'],
            is => 'ro', 
            isa => 'ArrayRef[Int]', 
            default => sub { [] },
            handles => {    
                get_array => 'get',
                count_array  => 'count',
            });

sub sortData{
    my $self = shift;

    print "Sorting data..\n";

    _sortAlgorithm($self->array);

    # ...
}

# Protected method here is the actual algorithm
sub _sortAlgorithm {
    die 'You must override _sortAlgorithm() in a subclass';
    # but Moose will always call the superclass which then makes it die
} 

SubClass

package OrderedSort;
use namespace::autoclean; # Trims EXPORTER 
use Moose;
extends 'AbstractSort';

# Override and mmpl _sortAlgorithm
override _sortAlgorithm => sub {
   my $self = shift;
   # ....
};

before '_sortAlgorithm' => sub {
    my $self = shift;
    # ...

    return;
};
