My suspicion is that the tech got interupted post testing/pre tightening and forgot about it. Not a major error and one that is easily fixed - but do not leave them only finger tight.
I guess this is one area we are just going to have to differ. I see the failure to properly tighten critical fittings that can lead to catastrophic failures as a very major error that is simply unacceptable. I put it in the same category as the tire shop leaving your lug nuts loose.
