Yeah, but its difficult to write a SIMD / AVX512 routine if things aren't in SOA format.

I can see how this approach described is "vector-like", even if the vector is this... imaginary unit that's parallelizing over the branch predictor instead of an explicit SIMD-code.

This "vector" organization probably has 99.999%+ branch prediction or something, effectively parallelizing the concept. But not in the SIMD-way. So still useful, but not what I thought originally based on the title.
