You didn't quote the sentence immediately before that:

To clarify this a bit, there are two different types of 64-bit linux 
systems out there.
One is the bi-arch ("hybrid") system that has normal 32-bit libraries in 
.../lib and 64-bit libraries in .../lib64. This is what the flgrx driver 
is built for.
Then there is the other variant called "pure64" where .../lib contains 
only 64-bit libraries (debian for amd64 is pure64, hence the note on 
Flavio's page). On such a system, the actual 32-bit libraries are 
located somewhere else, in debian's case under /emul/ia32-linux.

Yes, that would be exactly what "a link from /usr/X11R6/lib64 to lib" means.
