Well, You can`t find this particular method in the help document. This is just understanding RC+some math, but it is pretty simple.
You want to shift each row by the half size of the one `smaller brick.
I`m using two separate bricks with exported X Size for calculations and then Compose them into one `group`. Then with the transform operator just translate it for the half size of the second brick.
At one point you will get to the repeating pattern (distance) and that is the `K` value.
Second, I used this `K` with mod(####,k) formula to reset the `X Fixed Transform` value otherwise I will get a linear transform.
If I found time I`ll try to make a video clip for you to make it easier to understand. Right now I`m in the middle of a few parallel projects and there is no time.
