From org.el:
--8<---------------cut here---------------start------------->8---
(defun org-back-to-heading (&optional invisible-ok)
"Call `outline-back-to-heading', but provide a better error message."
(condition-case nil
(outline-back-to-heading invisible-ok)
(error (error "Before first headline at position %d in buffer %s"
(point) (current-buffer)))))
--8<---------------cut here---------------end--------------->8---
Frankly, I don't see the point of nesting `error'.
Best,

One is matching the signaled error, and the other is re-throwing the
error with position and buffer information included.
