As a man with straight hair that is usually on the shorter side I can tell you I get a distinct difference between shampoo only, and shampoo then conditioner. I get a similar effect from 2 in 1 that I just use that… I notice a benefit from 2 applications though (people will actively comment on how soft it looks and ask if I did something different), it is diminished after 2 though.
I try to only wash my hair a few times a week though when it feels too greasy (longer it gets the quicker this happens) and water isn’t enough, usually don’t bother with the double wash though.
Yes, it certainly isn’t universally true that not all short hair needs conditioner but it is more universally true that long hair does which is why women have more hair products.
Length and type of hair is what matters. Men with a typical short haircut with straight hair do not benefit from conditioner.

I feel marketing is a not insignificant difference as well. But if it helps people feel better about themselves who cares.
