Replication guides's function has been changed?

Hi all. I’m studying about Replication guides.

I have a question. In the newest version of dynamo, Is there any change about function of “Replication guides”??

The First Image is what I’m trying now. and the second image is what I found in the internet for studying. Then when I follow the second image’s logic, my result is different. actually my result is same with using x<1>.y<2>,z<3>…

So i just wonder. If i made some mistake or the function of replication guides has changed… please let me know.

the second image

No mistake, the working of replication guides has changed
