The link you posted above makes no mention of Camp 4 or environs at all, only Glacier Pt (which I agree is a scary place - only climbed there once but it was pretty spooky to hear about the 2008 rockfall).
Like I said, there are no big cliffs close to Camp 4 - in fact directly behind it is the gully / scree slope that the initial switchbacks of the Upper Yosemite Falls Trail go up. A little suspicious that they'd be closing parts of Camp 4 due to rockfall danger without also closing that (popular!) trail...
