Unilateral profile setup/Question

Unilateral profile setup/Question

Hello all,
I've attached some pictures of a profile that I'm trying to measure accurately.  I'm questioning many things with this situation.  Can anyone give me some insight on their opinion with my setup?  The print says unilateral but from what I can find online and in the forums here, I question if that verbiage is correct?  I could really use some expert advice on how to handle the two profile callouts in the print photo.  Please let me know if I'm approaching this correctly with what I show in the other photos "cmm_image1&2".  Thank you very much!
