That means when you come to the <tt> line in the first macro, and have a player targeted, the macro tries to cure that player's target. If they have nothing targeted, the line is skipped. If they have a hostile target, it behaves as if you had that hostile targeted and were simply casting the spell, which means you cure yourself. Same thing with the <mo> and <t> lines if you mouse over or target a hostile, respectively, yourself.
Wow this helped out alot! I didn't know that about the default curing when targetting something hostile. Now I have to figure out if it's worth even having the macro because I wouldn't want to have two macros for the same ability (depending on the target). That would defeat the purpose of macroing >.<
