If this is repeatable, I would take it in for assessment.

This is a new Power Management change introduced with update DL1609. You'll also notice now another quirky issue that if you close your lid and put your MacBook to sleep, when you plug/unplug your power adapter the MacBook wakes up for a few seconds. Yep, it's annoying. Blame Apple.
Also, the deep hibernate, even though is set to engage after 4 hours of sleep on both AC and Battery, ONLY works when the laptop is on AC power. So, you will see it hibernate like this only when it's plugged in to charge and has been sleeping for a minimum of 4 hours. Once it reaches that time, it hibernates and the next time you wake it, it'll look like what you see on your screen for a few seconds (like 20-30 or so).

What is your source for that information?

Umm, ME. That's the source. That and Apple because they're the ones that indicated that the PM changes implemented were part of that update. It was pushed out back in November and just recently, more and more people are noticing this new behavior. I noticed it 2 days after I first installed this update back in November and I've been working with them since then to try and get an explanation on why it's more efficient to "wake" the system out of sleep when you plug/unplug the AC adapter from it. In addition to that, I'm also waiting to hear from them why when both AC and Battery settings in PM are "by default" set to hibernate after 14400 seconds (4 hours), why it only happens when it's on AC and not on battery. They currently have no answer to this. I don't think they "get it".
