Yes, it's retarding the cam from it's parked position. Unlikely you'll see any gains from running more than what's in their table, as they likely did the dyno sweeps to determine the optimum torque for each rpm/load to create it. May effect timing, since it's impacting VE.
Make sure you copy/paste it to the medium and high tables as well. Retarding the cam reduces exhaust piston to valve (PTV) clearance. Luckily it didn't seem to be enough in your case to cause contact in combination with the larger camshaft. I'm referring to the cruise and part load sections of the factory table where it's double digits.
