That is my major point of contention regarding the difference between the two methods for making WMO.
I agree and I would expect some significant differences in their respective behaviors.
After I reviewed an old thread from the WMO forum about patents and inventions, I ran across a third method, in this post by DBClemmons
where he quoted Grumbacher Max methodology, saying that no surfactant is used at all.
They claimed to be able to separate a water mixable faction of normal binding oil and achieve water solubility.
Maybe this could be a reason why they have gotten a less than glowing reputation for their brand of WMO's
