Hello ASMapper, Thank you for your edit, and welcome to OSM.     
I see you edited the boundaries to match the dirt barrier that was made with bulldozers. While it is the correct, but this dirt barrier line was made by the Iraqi Army inside Iraq with 100 meters I believe inside Iraq, not inside Syria like the way you did, so the correct way is to move the line from the eastern side of the barrier to the west part of the dirt barrier by around 100 meters.        
Let me know if you can't do correct it so I can help.    
Best Regards.
