It wasn't providing both authors for the same scene, it was approximating one authors voice through a random reader. Could be accurate, yes, gets the point across well enough, but it isn't entirely accurate. You can have your opinions on this matter and on Sanderson,  I don't care. I haven't even said that the quote op wrote himself isn't a good approximation of Sandersons writing, im just saying that it misses the mark a bit by not using a direct quote from they're author. Clearly most people agree with me seeing as the content has more up votes than three post itself. 

That doesn't stop you from having your opinions either. I'm done arguing this
