Probably because the macro language is not Java.  In Java, "==" tests for identity.  Two objects compare as "==" if and only if they are the SAME OBJECT.  Two strings that have the same contents are not the same string.

I'm not an expert in the macro language, but I suspect that in a macro "==" test for equal VALUES, so two distinct
strings that happen to have the same sequence of characters are "==".

In Java, testing for equal values requires "equals".  Question: is there an "equals" in the macro language?

The question of "equality" vs "identity" is a tricky one.  Different languages answer it in different ways.
