Shifting to d3 won't do any harm unless you were going extremely fast. You are just doing manually what the trans normally does automatically. I agree that doesn't sound right for DFCO though. Not all engines have the same parameters for DFCO (my Rondo will only cut fuel below 2000 rpm) but it won't require any abnormal input from you to cut in. If you meet the conditions, it will work.
