Uploader code question

[Anastasia Cheetham]

I'm trying to document how the Uploader works (for a tutorial), and  
I've come across something I don't understand. I'm hoping someone can  
help clarify.

In the bindEvents() function, the upload and result functionality are  
both bound to the relevant button click handler thus:

   $(button).click(function() {
     if ($(uploader.fragmentSelectors.upload,  
uploaderContainer).css('cursor') === 'pointer') {
       uploader.actions.beginUpload();
     }
   });

I'm not understanding why the 'cursor' css property is being checked?
