Is it by design that FastPFor cannot decode data encoded by SIMDFastPFor?

I have tried to use SIMDFastPFor<4> to decode data encoded by FastPFor<4> and it got wrong result. And vice versa. Is it by design or a bug?

Unless otherwise stated, the binary formats of all codecs differ. They are not meant to be interoperable.
