If you look at the screenshot for the older PC version you may spot a couple of differences.
The sample video is titled "Google Recruiting Video" in the PC version, but on the Mac version the video is called "An Inside Look At Google."
You will also notice a difference in the thumbnail images at the bottom of each video. On the PC version you will see that Sergey has got his eyes closed in the sampled frame, but in the Mac version this frame has been replaced with one that shows Sergey with his eyes open.
The Google PR Police have obviously extended their power base in Mountain View.
(I have added the latest Google accessories to Simply Google).
