Not sure what using the eyedropper has to do with this process--you can just choose the material from the browser right there.
It's a quick way of showing someone the very basics of how materials can be sampled from one face and placed on another, and in the process show the material in the 'in model' section of the browser. If he knew that he could choose from the browser to begin with he wouldn't have needed to ask.
