Given that the kinematics (pos,vel) at time t depends on previous kinematics. I don't see how an integrator could compute the motion without previous velocity (the result would be independant on e.g. initial velocities!). Yes, different schemes could need vel(t-2dt) instead of vel(t-dt) (or both of them), but you always need a "previous" velocity.
