     This extension guarantees uniforms always have the same locations.
 
     This allows the client program to know the locations of uniforms
-    without having to compile the shaders, link the program and query
-    the locations and therefore have no blocking calls when initializing
-    programs.
+    without having to wait for shaders to compile or GLSL programs to
+    link to query the locations and therefore have no blocking calls
+    when initializing programs.
 
     To be forward compatible the locations are provided through the
-    function GetUniformLocationsCHROMIUM but they can be provided
-    even before linking a program and therefore do not have to wait
-    for compile or link completion to return results.
