Is this Datum Reference Frame Realistic

Is this Datum Reference Frame Realistic

Hello,
I am in the process of inspecting this part and I am starting to question this DRF. Is this even possible. Seems like it is trying to constrain more than 6 degrees of freedom. Maybe I am wrong or missing something. 

I also tried to Draw Datum Target "D" in this snip for reference. 

Let me know your thoughts.
