They're the same thing.

From http://www.unix-systems.org/unix98.html: 

    UNIX Бо 98 - the latest version of the Single UNIX Specification
                integrating the industry's Open Systems standards.

Follow that to the download page at

       http://www.unix-systems.org/online.html

and what you get is the single UNIX specification version 2.  Why they
adopted a naming scheme from a company whose ambition is to kill
anything UNIX (or even Unix :-) is a puzzle I haven't attempted to
solve.
