Simulate substeps limits the velocity of particles on the first frame they're affected by operator to simulate the effect of them being born at a negative subframe whose length is a random value between 0-100% the length of any given timestep.
That may be a confusing mouthful, but it basically just randomizes first-frame velocity to prevent stepping artifacts that can occur when simulating with large (ex: whole frame) timesteps. However, in your case it's not useful.
