Agreed, as an Admin having alternate browsers available in in an environment can be incredibly beneficial. Security/patch wise it's a real pain to maintain Firefox so this is a big advantage for Chrome.
Applying updates is nearly painless in Chrome. Just hit "update google chrome" and the update is applied, the browser is restarted in a matter of seconds with all your previously open windows and tabs are retained. The only downside is youtube videos you had open might automatically restart. Firefox has a similar update process but it's so much clunkier that it eats up far more time and effort. IE's update process is a joke in comparison to both (sometimes requiring a full restart of your system).
I think he is specifically refering to updating it in a managed environment. Applications set up correctly (e.g. Microsoft Office) can have updates pushed out over the network to all users, automatically. This isn't so easy with Firefox, but it should now be easy with Chrome.
