I think it's related to evaluation in the *scratch* buffer.  Try typing
M-: and then eval the expession there -- it works as advertised.

But how exactly the *scratch* buffer makes it fail, I'm not sure.  I
tried to eval (previous-line 3) in the scratch buffer, and it dutifully
went up some lines before inserting "nil" (the return value).
