Vic, You are entirely correct - and I have long advocated thinking about the 'ground' terms separately. It should be common knowledge (but it isn't) that one 'ground' can be at a different potential than another 'ground'. I learned early in my hamming days because we often referred to 'chassis ground' which was a common wiring point and often had nothing to do with any earth ground. (That was before the time of the 3 wire wall outlets!!!)
