This is just a case of OS evolution.  /sbin used to be the place where 
the statically linked recovery things would be placed, in case the 
shared libraries got hosed.  The only things that needed to be 
statically linked though, were system utilities, which is why people 
probably started to associate the "s" with system, rather than static.

When this happened, you started to see the duplicates that used to 
exist in /bin (or /usr/bin) and /sbin disappear.  Since you still need 
a place to have statically linked recovery utilities, /rescue was 
created.  Now you see the duplicates in /bin (or /usr/bin) and /rescue
