Well, as usual, Google's immediate help -- via a search pop-up from the Account settings page that links to the page where this setting is presented; there is no help linked/provided on the actual page -- is useless. Searching from the Google home page, I ran across this chain of links. It still provides no description of whether/when this setting is activated. As my tab, bookmark, etc. settings did not carry over automatically to this instance of Chrome when I started using it, I am brought to conclude that this morning's annoying and unwelcome pop-up did indeed turn on this synchronization setting for my account. And that the thereupon/thereafter presented "Undo" button was bullshit -- it didn't undo the synchronization setting.
