Assumption is correct, break in was done with both springs installed. Not too sure on what spring pressure is currently being used. I ordered spring pressure tool to verify but cam calls for 360 lbs at full lift
I've broken in cams with dual springs for years. Never had a failure. Not one. As long as you use the right break in lube and an oil high in zinc content and follow the correct break in procedure, you won't have a problem.
