The tags are only evaluated when you "use" the macros to create/update them. That is why you cannot use the master / slave tags if you want to switch master. This limitation extends from a limitation of the Blizzard API (no changing macros in combat).
You should just be able to use the one macro for both master and slave.

I know it s a bit to get your head around, but I like it that you are trying out Jamba-Macro.
