I found the reason. They don't have it as maxlife, only Valvoline high mileage.
Facing basic price parity, I will weigh the options.

AISIN is the largest manufacturer of Automatic Transmissions in the world. By applying decades of knowledge, experience, and development in cooperation with vehicle manufacturers, AISIN has developed a state of the art ATF that will maximize performance and longevity of
automotive transmissions.
I mean, they're certainly a reputable company and certainly have some familiarity with various transmissions (ironically, not Honda transmissions as Honda builds them in-house).
Generally speaking, engine and transmission manufacturers draw up the specifications for the lubricant and do not blend their own lubricants.
The engineers communicate with additive company labs.
An additive company formulates and tests the complete additive package in-house .
A blender then takes the additive package and blends base oils with it.
Blender then has the finished lubricant tested and results go to OEM for approval.
If everything is hunky-dory, OEM approves blender for sole-sourcing FF and for dealers.
Example: Many of the later Dexron fluids for GM were developed by Afton in cooperation with and speced by GM Driveline Div. engineers.
PetroCanada then took Afton's additive packages and blended the finished ATF for FF and to dealers.
Thereafter, other equivalent fluids come into the market by licensing the patents, or purchasing the additive package, or by reverse engineering.
Blenders can only receive a certification and OEM licensing after tests results are approved by OEM.
