Reverse engineering the mindset....
In the 90s, a cryptography paper was published that more quickly brute forced DES (standard encryption algorithm back then) using SIMD across 64-bit registers on a DEC Alpha.
There is also the 80s Connection Machine which was a 1-bit SIMD x 4096-lane supercomputer.

It sounds like this guy read a few 80s or 90s papers and then got stuck in that unusual style of programming. But there were famous programs back then that worked off of 1-bit SIMD x 64 lanes or x4096 lanes.
By the 00s, computers have already moved on to new patterns (and this obscure methodology was never mainstream). Still, I can imagine that if a student read a specific set of papers in those decades... This kind of mindset would get stuck.
