Inheriting position and velocity

I am spawning multiple particles around the particle that dies in contact with a sphere. These particles inherit position and velocity of dead particle. New particles collide and conform to the sphere. The problem is that they spawn with some offset that is somehow linked with Z axis velocity that is set on their spawn - it's shown on the video.

Why is this happening? Is it some form of preventing them from intersecting with the sphere collider?
I need them to spawn on the same Z axis position as their parent and then, with multiplied Z velocity hit the sphere and go in different directions.

There is a graph that is responsible for particles that are spawned on around dead particle
