I think this has been removed after ajc 1.0.6.
If I remember well, it used to match the last of the list in case of 
ambiguities. I think this could easily cause some problems, especially 
if args matches the runtime type and not the signature type. For example:

Using a method like this:
   void test (ClassA a, String s, Object obj, ClassB b) { ... }

used like this:

test(a,"A",new Object(),b)
test(a,"A","B",b)

a pointcut like this:
   pointcut(String s): call(* *.test(..)) && args(..,s,..)

would bind s to "A" in the first call and s to "B" in the second.
Not really intuitive...
