Moose (2.1604) behaves the same way: 
use warnings;
use strict;
use feature qw{ say };

{   package MyRole;
    use Moose::Role;

    sub where { 'Role' }
    sub role  { 'yes' }
}


{   package MyClass;

    sub new   { bless {}, shift }
    sub where { 'Class' }
}


{   package MyHeir;
    use Moose;
    extends 'MyClass';
    with 'MyRole';
}

my $h = 'MyHeir'->new;
say $h->$_ for qw( where role );
__END__
Prints:
Role
yes

So the behavior is at least consistent albeit not adequately documented.
