Subject: Routing code question

In routing.rb, what is the purpose of the following piece of code:

class Regexp #:nodoc:
  def number_of_captures
    Regexp.new("|#{source}").match('').captures.length
  end


Does this method not always return 0?  It's always going to match ''
with the blank spot before the | and therefore will have no captures.
