 From the doc string for replace-string in Emacs 22:

   In Transient Mark mode, if the mark is active, operate on the contents
   of the region.  Otherwise, operate from point to the end of the
   buffer.

So if region is visibly marked then the replace is only done in the 
region. (This is true if you use cua-mode for example.)
