ORing in recipies

In the (wonderful) Quick Start guide, several different methods for 
ORing are discussed or linked. After reading through I was under the 
impression that the following should work to match the following empty 
subject cases:
:0
* ^Subject:[ ]$ | ^Subject:$ | ^Subject:[ ]*$ | ^Subject:[ ]..$ | 
^Subject:[ ]\(no subject\)
$
{
  :0 c
  | formail -r | formail -xTo: | perl ./doError.pl junk errEmpty

  :0
  ! parser(_at_)miach(_dot_)dartmouth(_dot_)edu
}

But they don't seem to match. I'm sure if I split them into mulitple 
rules it would work, but I was hoping to keep them together for 
simplicity's sake.
