No, it does something very different to achieve basically the same effect. It 
simply widens the margins, which aren't used to display text, so the text area 
is reduced.

Doing this in the line-wrapping code (i.e., make the wrap coordinate 
controllable by the user) might be the better way to implement it, because it 
should theoretically become possible to exclude certain parts of the buffer 
from wrapping, i.e., tables or source blocks in Org files. (I've had this 
request for visual-fill-column-mode once or twice, but it's simply not 
possible.)

But if the line-wrapping code is already devilishly complicated, as Eli says, 
it's probably unlikely to happen...
