Allowing that the document is directed toward the layman, it seems fair.
It's good to note the reference to isolation transformers and the explanation that inclusion of these on the power feeds will not eliminate problems with ground loops.
The latter requires either electrical isolation of data paths between devices (e.g. opto-isolators) or the separation of protective and signal grounds.
