Pedant point: POSIX incorporated all of SuS some years back; the result is called POSIX. (Confusing, I know.)
Well, to be extrememly pedantic, the work of the Austin group consolidated earlier POSIX standards and SUSv2, to create a new standard that defines two levels of conformance: base conformance (aka POSIX.1-2001), and XSI (X/Open System Interface) conformance (aka SUSv3). So the result is called both POSIX and SUS.
