I thought the same thing. In roaches, it usually appears that the whole body is a different gender, lengthwise.
Gynandromorphs are not always bilateral. For example, there are mosaic gynandromorphs, with male and female characteristics scattered among the various body parts. I believe this is the case here. The thing dorsad the ovipositor valves cannot be the spermatophore (if we assume that this is indeed a freak female): because the female part of the genitalia is so distorted, I doubt that a normal male could lock with it and leave spermatophore. Besides, in what I assume to be the male part of the genitalia I can see all three complexes of genitalia sclerites (although size of the pictures is too small to tell the details).
