Mordhau and BF5. Why are the vertical and horizontal sensitivities different?

[Jeffy14]

Hello everyone,

I hope someone can help me. 
I was playing around with the sensitivity for Mordhau to match the one I have in BF5.
I was surprised because the Calculator tells me to put different values for horizontal and vertical.
Should they not be the same to have a 1:1 move ratio, that is a move from the left to the right should be similar in distance to a move from top to the bottom?
Thank you for your help. Screenshot attached.

Many Unreal Engine 4 games scale the X sensitivity to 70% of the Y sensitivity, so whenever there's support for different X and Y sensitivity the calculator will fix this issue by giving you the 1:1 sensitivity for both axis.
