Yes, it follows you, shows this in the video in fact.
What it does not do is give you voice turn by turns. Or traverse your route, it will, however, keep your current position in the center.
I don't think this is Apple's problem to deal with, in any case. Apple is not a mapmaking company, nor have they ever developed GPS navigation software. Google has a Map feature which can be accessed through the iPhone, but was never intended to be a turn-by-turn navigation program. So, for now, the ball's in Google's court; will they get this going on the iPhone or not?
If Google doesn't do it, it's only a matter of time before TomTom or Magellan or someone else makes an App for the iPhone with this feature.
