Ofcourse it's going to happen, thats what ur plugin function does. It's not even considered a "problem".

[Natsheh]

PHP Code:

stock create_velocity_vector(victim, attacker, Float:velocity[3])
{
    if(!is_user_alive(victim) || !is_user_alive(attacker))
        return 0;

    new Float:vicorigin[3], Float:attorigin[3];
    entity_get_vector(victim, EV_VEC_origin, vicorigin);
    entity_get_vector(attacker, EV_VEC_origin, attorigin);

    new Float:origin_diff[3];
    for(new i = 0; i < 3; i++)
        origin_diff[i] = vicorigin[i] - attorigin[i];

    new Float:fLen = get_distance_f(vicorigin, attorigin);

    if(fLen <= 0.0) return 0;

    for(new i = 0; i < 3; i++)
    {
        origin_diff[i] /= fLen;
    }

    new Float:knock_force = get_pcvar_float(cvar_knock_force);
    velocity[0] = (origin_diff[0] * knock_force );
    velocity[1] = (origin_diff[1] * knock_force );
    velocity[2] = (origin_diff[2] * knock_force) + random_float(200.0, 275.0);

    return 1;
} 


Here you go this function should make more sense now, make sure to post in the proper section..
