Davey....really depends on the local office and/or the individual who comes out. They have some great arborists....and some other people on staff too. Hopefully you get the first. I think they are under more pressure than most to sell a little harder, so just be cognizant of that.

Why don't you check for the stem girdling root (last photo) or plastic twine from the original transplant.
