Yes, a longer range site in distance will flatten out the trajectory, until you reach a certain point.
That point is determined by the distance of your visual line of site above the barrel bore.

I site in my rim fires different than my center fire rifles. I don,t see a need for my rimfire to cross above my zero'd line of site. My shots are just not that far generally. it hits zero once and then the poi starts to drop back down...

On my center fires I like to have the bullet cross over the first zero'd line of site to about 2.5 inches high before it starts to drop back through the second zero,d line of site farther down range. Where ever distance those zero'd points of impact end up being is secondary to me.
