What is the return value of DEBUGHELPER::GetProcessorType() while using Visual Studio 2012?

When debugging native 64 bit applications while using Visual Studio 2012, the return value of DEBUGHELPER::GetProcessorType() seems to be 9 (AMD64) . But the return value is 2 (AMD64) for Visual Studio2010. Can this value (i.e. 9) be used to judge if the application under debug is a 64-bit process?

Thanks.
