You can only get scalars using the arrow syntax, you cant get multiple values

my $sth = { NAME_uc => [ 1 .. 2 ] };
print join "\n" , $sth->{NAME_uc}[0 ,1 ];
__END__

my $sth = { NAME_uc => [ 1 .. 2 ] };
print join "\n" , @$sth->{NAME_uc}[0 ,1 ];
__END__

That is why you need curlies

my $sth = { NAME_uc => [ 1 .. 2 ] };
print join "\n" , @{ $sth->{NAME_uc} } [0 ,1 ];
__END__

The arrow-less way

my $sth = { NAME_uc => [ 1 .. 2 ] };
print join "\n" , @{ $$sth{NAME_uc} } ,''
