If I recall when I first started at Google in 2011 my workstation had some kind of background clipboard management which prevented certain classes of copying between browser sessions, etc. In a similar fashion if you accidentally typed your password into a non-Google service, it would notice and expire that password. (I can't recall if this was only at the browser level, or if it happened in terminal sessions, too.) Later they loosened up some of the latter stuff because the importance and weight of passwords themselves was reduced. (I also started just a few months before they implemented the e-mail "expiry" policy which prevented people from keeping old emails, cuz, y'know, they kept leaving stupid paper trails there that got them in legal trouble.)
