At the risk of being a pain, the Modified Date column values didn't change when I replaced the original code, minus the two lines.

Here's a thought.

I could add code to the RefreshFields2 macro to first find all instances of a word - I'm pretty sure "overview" is in every Word doc in this folder structure - and replace it with the word "overview", save the document, and then second to process the code that actually updates the fields? If I did that, at least I could verify the Word documents were actually being updated...
