Thanks.  I decided to clarify this in a slightly different way, by
adding the following sentence after the description of the matching
process:

  If @code{auto-mode-alist} has more than one element whose @var{regexp}
  matches the file name, Emacs will use the first match.

With that, I'm closing the bug.
