Don't you just love it when you find stuff like this! I am also not too sure about those home inspections (HI). My son bought a house last year and there was a ton of violations and mistakes. Now granted a lot of the violations were open splices and some of them were behind the dry wall. The HI could not have seen those problems, but when he and I were walking around the house, and he looked into a sub panel and the neutrals and grounds were tied to together, he thought that it was OK. I politely told him that it was a violation of the NEC.
