Not true. On 5.005_03 try this: 
my $foo = be({name => "foo"});
my $bar = be({name => "bar", data => $foo});
my $baz = be({name => "baz", data => $bar});

sub gotcha {
  $bar->{"bar can't go"} = "until this function is cleaned up";
}

sub be {
  return bless shift;
}

sub DESTROY {
  my $self = shift;
  print "$self->{name} died\n";
}

__END__

on 5.005_03 for me prints:

baz died
foo died
bar died

Note that $foo is going away before $bar. Remove the function holding $bar to global destruction and everything will clean up properly. Make them all global and you will again run into trouble.
