So, what you say is that even if i place the saddle in identical position and that exactly from bottom bracket and stem to saddle nose I will have to push it backwards on the straight seat post to get similar position as with the 20mm setback seat post?

If the saddle is in identical positions, the straight post will clamp 20mm further forward than the setback post. That's what setback is.
Sometimes, a particular saddle position won't work with both types. My saddles, because I have mostly bikes with steep 74 degree seat tube angles, need to be clamped toward the front of the saddle rails to get into correct position. That is on setback type seatposts. If I tried to do that with a zero setback post, I would have to mount the saddle about 20mm too far forward to get the rails to the post clamp.
This is a rather extreme example, but if this is your position, how could you possibly use a seatpost where the clamp is even further forward?
