It doesn't for me. I thought that meant that if one has more than one  
static constructor in a module then they run in lexical order. For example  
...

   module test;
   class Foo
   {
     static this() { ... }
   }
   class Bar
   {
     static this() { ... }
   }

   static this() { . . .}

In this case, Foo's ctor runs first, then Bar's and finally the module's.

The spec does not mean that one can have multiple class ctors per class or  
module ctors per module.
