debug-safari sets the WEBKITLIBRARIESDIR environment variable just for  
the VS process it launches.

http://trac.webkit.org/wiki/BuildingOnWindows#BuildingfromwithinVisualStudio 
  explains this environment variable.

The script is behaving as expected.

Perhaps your confusion comes from not knowing that it is possible to  
build WebKit without opening Visual Studio. The instructions that  
start at <http://webkit.org/building/tools.html> take you from  
installing Cygwin through building WebKit and running Safari, all  
without opening Visual Studio. The debug-safari script is meant to  
complement this workflow, by allowing Visual Studio to be launched  
correctly for debugging Safari/WebKit without the user having  
configured his/her environment for the WebKit VS project files.
