It took me a couple of minutes to notice it but I think
I see your problem. The first box is not built at xyz*0.
Then a rotation has been applied to it. It's no longer where
you expect it to be and the 2 boxes are not touching.

I haven't tested this theory and I may be full of ____
but it seems plausible.
