Why are the hooks on the rear of Blum slides different on the left and right sided slides? The photo is of Movento slides, but I think I remember Tandem being like this too.

I'm going to be installing them and far as I remember my Blum boring jig bores the hole in the same position on the back left and right of the drawer box. Been a while so going on memory here. I'll check it out tomorrow.
So what's going on here?
