For it to be scientifically accurate of a comparison, the ratio of weight:human needs to be equal to that of rider:horse, not a direct flip.
In case my phrasing is confusing, to illustrate what I mean here is an example: a 200lb horse carrying a 100lb human is equivalent to a 100lb human carrying a 50lb weight.

Things don’t scale linearly like that. Many things are proportional to either the surface (so x²) or volume (x³) or complex combinations of those.
