It doesn't. The string is a visual aid. If I wrap a string around the exterior vertices of the frame and stretch it tight, the string describes the frame perimeter. Not "is", "describes". A suitable comparison: You getting fitted for a suit--are you trying to say that because a tape measure is wrapped around your waistline, it is your waistline? Didn't think so.

Bear in mind, I've been dealing with bumper rules since '06. Some things are obvious to me because I've been dealing with 'em so long, but that particular definition/description has been in there since at least '08, if not '06. (I can't quite remember whether "bumper zone" or "frame perimeter" came into play first, or if they came in at the same time.) The key thing about the bumpers is that they serve 3 purposes: Protect the robot against impact with other robots/field elements, Identify the team by number, and Identify the alliance by color. If you've got a suggestion for the GDC that will result in looser bumper rules, while still fulfilling these three purposes, I suggest that you let them know. With all the restriction-easing going on, they might welcome the suggestion as one less place the inspectors have to inspect.
