Essentially if they both have the same underlying operation there is no apparent constraint or differentiation. It may or may not immediately prove anything but it suggests there isn't any reason to believe in inherent differences - check elsewhere for proof.

A clear disproof or proof would involve observing a hard constraint of some sort.

For a blatantly counterfactual analogy imagine that they found neural patterns for math were literally the same as computer processors done in brain cells like bored engineers implementating computers in Dwarf Fortress or Minecraft. They could decode patterns and found human calculations involve bit registers in their head - men fit between 3 to 6 base five "bits" directly and women have 2 to 5 base six "bits" as size constraints prevent fitting more in. They found larger numbers were done via piecemeal operations over a memory map slowing things down and increased clockspeed was possible but would literally cook their brain. The upper bound for men in this bizzare hypothetical world would be higher.
