As we have it "2" indicated stderr, but "1" indicated a file named 1, and "&1" indicated stdout. How would I know when to include "&"?
Well, on the right side of > and < there can be a filename, so the & prefix indicates it is a file descriptor.
On the left side it is clear that it's a file descriptor, so the bare number does it.
Note that > is identical with 1> and < is identical with 0<.
