No where in that article does it say it's ok to only serve the snapshot to googlebot. Serving different content to googlebot than what you serve to users is called cloaking and is against their guidelines: https://support.google.com/webmasters/answer/66355

I've invested a significant amount of time in this topic and would love if you were right, but I've never seen the money quote that it's ok to do this. In fact, everything I've read says that you have to treat search bots the same as you treat normal users.
