I don't own the shorts, but your question piqued my interest, so I had a look at the website.
If you're referring to the spot where the black fabric meets the grey - with what appears to be reflective piping at the edge - I think you'll find that's actually just for ventilation and to allow freedom of movement. I have similar vents on the upper back of a couple of running & cycling jackets.
I could be wrong, though.
Edited to add: the manufacturer's description doesn't say anything about pockets, either, and that would definitely be a feature they'd mention.
