Rather, they are joined together in literally one joint entity made out of both of them into one body. It might appear as if calling one the front and the other the back is a spatial description, but the truth is that they are not front and back in the same sense as we will be using these terms later. Rather they are literally like two simple entities which, through being combined, become one body made of both of them.
Both are compounded together in every place with no way of separating them. We can only say in general terms that in every place where the female is found, it is considered the back of wherever it is. (In other words, in every part of Atik there are male and female aspects, and in relative terms the female is “behind” in relation to the male. The female thus has no specific place, which is not so in the case of Arich Anpin, where the female is on the left.)
