Rails - Nov 2005 - validates_associated

I have an db table that associates two things from the same table.

people_alt_people
-----------------
person_id
alt_person_id

So my ActiveRecord looks like:

class PeopleAltPerson < ActiveRecord::Base
  belongs_to :person
  belongs_to :altperson, :class_name => ''Person'',
:foreign_key =>
''alt_person_id''

  validates_presence_of  :person
  validates_associated   :person
  validates_presence_of  :altperson    # HERE?
  validates_associated   :altperson    # HERE?
end

It''s the last two lines I''m asking about.  Can the
validates_associated
macro be used in this situation?  i.e. where a table has two references 
to the same table.
