Visual Assist X - Jump to implementation (alt+G) doesn't work on overloaded methods

Question

I have a class with two methods like:

class MyClass
{
 void method(int x);
 void method(int x,int y,int z);
};

Using Visual-Assist, if I put the cursor on one of these lines and hit ALT+G, which should take me to the implementation, instead I get a little popup asking me which implementation I want to go to. Why? Can't it tell?
