See the R manuals: these have ever since R 3.1.0 explained this. 
Currently at 
http://cran.r-project.org/doc/manuals/r-release/R-admin.html#Installing-R-under-OS-X 
: the main advantage is more modern compilers (those used for Snow 
Leopard date from 2007) with support for current language standards 
needed by some packages.  (R itself uses very little of the OS X APIs: 
R.app uses more but the same code is used for both builds.)

'In the long term' none of these versions of OS X will be supported (by 
Apple or R): expect binary package support only for >= Mavericks in R 
3.2.0 next Spring.
