Enlarge (Su): As a swift action you can enlarge yourself for 1 round, as if you were the target of the enlarge person spell.
You use the rules of enlarge person.
The intent is that this doesn't work. Druid's wildshape is a (Su), and it still follows the rules of polymorph effects. In fact, it wouldn't work at all otherwise.
Is there a size increasing effect in play and a polymorph effect? Great, they don't work together. That's the purpose of that line.
